How to Increase Mailbox Size in Office 365

If you are using Office 365 and find that your mailbox is constantly running out of space, don’t worry! There are ways to increase the mailbox size to accommodate your growing needs.

Office 365 offers different subscription plans, and the mailbox size may vary depending on the plan you have. By default, the mailbox size limit in Office 365 is set to a specific value. However, with a few simple steps, you can increase the mailbox size and enjoy the benefits of having more storage for your emails.

To increase the mailbox size in Office 365, you can either upgrade your subscription plan or opt for additional storage add-ons. Upgrading your subscription plan allows you to have a larger mailbox size, giving you more room to store your emails and attachments. With additional storage add-ons, you can increase your mailbox size without changing your existing subscription plan.

Remember, having a larger mailbox size not only allows you to store more emails, but it also ensures that important messages and attachments are not deleted due to lack of space. With these simple steps, you can easily increase your mailbox size in Office 365 and ensure that you never miss an important email again!

Check Current Mailbox Size

To check the current size of your mailbox in Office 365, follow these steps:

Sign in to your Office 365 account.
Go to the mailbox section.
Click on the mailbox you want to check the size of.
On the mailbox properties page, you will find the current size of your mailbox displayed.

It’s important to regularly check the size of your mailbox in Office 365 to ensure that you don’t exceed your allocated storage space. If your mailbox is close to reaching its capacity, you may need to take actions to increase your mailbox size to avoid any issues with receiving or sending emails.

Review Office 365 Subscription

When considering how to increase mailbox size in Office 365, it is important to review your current subscription plan. Office 365 offers a variety of plans with different storage limits and features, so taking the time to evaluate your needs can help you choose the right plan for you.

The first step is to determine the size of your current mailbox and how much storage space you require. Office 365 provides different mailbox sizes depending on the plan you have subscribed to. It is essential to check if your current plan meets your storage requirements or if you need to upgrade to a higher plan.

Upgrading your Office 365 subscription to a plan with a larger mailbox size can provide you with more storage space to store your emails and attachments. This is particularly useful if you frequently receive large files or have a high volume of emails that need to be archived for future reference.

In addition to increased mailbox size, upgrading your plan can also offer other benefits such as access to premium features like Microsoft Teams, SharePoint, or OneDrive for Business. These tools can enhance collaboration and productivity within your organization.

Before making any changes to your Office 365 subscription, it is recommended to consult with your IT department or administrator to ensure a smooth transition. They can guide you through the process, evaluate your storage needs, and help you select the best plan for your organization.

In conclusion, reviewing your Office 365 subscription is an essential step in determining how to increase mailbox size. By evaluating your current plan, understanding your storage requirements, and considering the additional features available, you can make an informed decision that will meet your organization’s needs.

Evaluate Storage Limits

When it comes to managing mailbox size in Office 365, it is important to understand the storage limits that are in place. These limits determine how much data can be stored in a mailbox and can vary depending on the type of subscription you have.

Default Mailbox Size

By default, each user in Office 365 is allocated a specific amount of mailbox storage. For most subscriptions, this limit is set to 50 GB per mailbox. However, it is always a good idea to check the specific storage limit for your subscription to ensure that you are aware of any differences.

Additional Storage Options

If you find that the default mailbox size is not enough for your needs, there are several options available to increase the storage capacity. One option is to upgrade your subscription to a higher tier that offers more mailbox storage. Another option is to purchase additional mailbox storage add-ons that can be applied to individual users or shared among a group of users.

Subscription Tier	Default Mailbox Size	Additional Storage Options
Business Essentials	50 GB	Purchase additional storage add-ons
Business Premium	50 GB	Purchase additional storage add-ons
Enterprise E1	50 GB	Purchase additional storage add-ons
Enterprise E3	100 GB	Purchase additional storage add-ons or upgrade subscription

Evaluating the storage limits for your Office 365 mailbox is essential in order to effectively manage and plan for your storage needs. Whether it is utilizing the default mailbox size or exploring additional storage options, understanding your storage limits will ensure that you can efficiently store and manage your email data.

Adjust Retention Policies

One of the ways to increase mailbox size in Office 365 is by adjusting retention policies. Retention policies control how long items are retained in the mailbox before they are automatically deleted or archived. By modifying these policies, you can potentially free up more space in your mailbox.

To adjust retention policies in Office 365, follow these steps:

Step 1: Sign in to Office 365

Go to the Office 365 sign-in page and enter your credentials to access your account.

Step 2: Access the Exchange admin center

Once you are signed in, click on the Admin app in the app launcher and then select the Exchange admin center.

Step 3: Go to the Messaging Records Management (MRM) section

In the Exchange admin center, navigate to the Messaging Records Management section. Here, you can manage retention policies for different mailbox users.

Step 4: Edit the retention policy

Locate the retention policy that is applied to your mailbox and click on it to edit the settings. You can change the retention period for different types of items, such as emails, calendar entries, and attachments.

Note: It is important to carefully review the retention policy settings and consider the impact before making any changes. Modifying retention policies may result in the permanent deletion of items.

Step 5: Save the changes

After adjusting the retention policy settings, click on the Save button to apply the changes to your mailbox.

By appropriately adjusting retention policies, you can effectively manage the mailbox size in Office 365 and ensure that important items are retained while unnecessary ones are automatically deleted or archived.

Archive Older Emails

If you find that your mailbox size in Office 365 is reaching its limit, one effective way to increase your mailbox size is by archiving older emails. Archiving older emails means moving them to an archive folder, freeing up space in your mailbox while still keeping access to them if needed.

Here’s how to archive older emails in Office 365:

Step 1: Set up an Archive Mailbox

Before you can archive old emails, you need to set up an archive mailbox. This is a secondary mailbox that stores your archived emails. To set up an archive mailbox, follow these steps:

Open Outlook and go to the “File” tab.
Select “Options” and then click on “Advanced”.
Under the “AutoArchive” section, click on “AutoArchive Settings”.
In the “AutoArchive” dialog box, check the box next to “Move old items to” and select a folder where you want to archive your emails.
Click “OK” to save the changes.

Step 2: Choose Emails to Archive

Once you have set up an archive mailbox, you can choose which emails to archive. To select emails for archiving, follow these steps:

In Outlook, go to your mailbox.
Select the emails you want to archive by holding down the “Ctrl” key and clicking on each email.
Right-click on the selected emails and choose “Move”.
In the “Move” menu, select “Other Folder”.
Choose your archive mailbox from the list and click “OK”.

By archiving older emails, you can increase your mailbox size in Office 365 and improve the performance of your mailbox. Remember to regularly review and update your archive mailbox to ensure it doesn’t become overloaded with unnecessary emails.

Note: It’s important to note that archiving emails in Office 365 may vary depending on your organization’s settings and policies. Consult with your IT department or Office 365 administrator for any specific instructions or guidelines.

Manage Clutter and Junk Mail

One important aspect of managing your mailbox size in Office 365 is reducing clutter and preventing junk mail. Clutter is a feature in Office 365 that helps to organize your inbox by moving less important emails to a separate folder. By managing clutter, you can keep your mailbox clean and organized.

To manage clutter in Office 365, follow these steps:

Open Outlook and sign in to your Office 365 account.
Go to the Settings icon and click on it.
Select “Options” from the drop-down menu.
Under the “Automatic processing” section, click on “Clutter”.
Toggle the “Separate items identified as Clutter” option to “Off” to disable clutter.
Click “Save” to apply the changes.

In addition to managing clutter, it is also important to keep an eye on junk mail. Office 365 has built-in spam filters that help to prevent junk mail from reaching your inbox. However, some junk mail may still slip through.

To manage junk mail in Office 365, follow these steps:

Open Outlook and sign in to your Office 365 account.
Go to the Settings icon and click on it.
Select “Options” from the drop-down menu.
Under the “Mail” section, click on “Block or allow”.
Add email addresses or domains to the “Blocked senders” list to block specific junk mail senders.
Click “Save” to apply the changes.

By managing clutter and junk mail in Office 365, you can effectively reduce the size of your mailbox and maintain a clean and organized inbox.

Use OneDrive for File Storage

If you are running out of space in your Office 365 mailbox and need to increase it, consider using OneDrive for file storage. OneDrive is a cloud-based storage solution offered by Microsoft as part of the Office 365 suite. It allows you to store files, collaborate with others, and access your files from any device with an internet connection.

By utilizing OneDrive for file storage, you can free up space in your mailbox and keep important files and documents securely stored in the cloud. This not only helps increase your mailbox size but also provides you with the flexibility and convenience of accessing your files anytime, anywhere.

How does it work?

When you save files to OneDrive, you can access them through the OneDrive web interface or the OneDrive app on your computer or mobile device. You can also share files and folders with others, controlling whether they can view or edit the files.

With OneDrive, you can easily upload files, create folders to organize your documents, and even sync files to your computer for offline access. This means you can work on your files even when you are not connected to the internet, and any changes you make will sync automatically when you reconnect.

Benefits of using OneDrive

Using OneDrive for file storage offers several benefits, including:

Increased storage: OneDrive provides you with ample storage capacity to store your files, so you won’t have to worry about reaching the mailbox size limit.
Collaboration: OneDrive allows you to easily share files with others and collaborate in real-time, making it ideal for team projects or document sharing.
Accessibility: With OneDrive, you can access your files from any device with an internet connection, making it convenient for working on the go.
Security: Microsoft takes security seriously, and OneDrive provides robust security measures to protect your files from unauthorized access or loss.

So, if you’re looking to increase your mailbox size in Office 365, consider using OneDrive for file storage. It’s a reliable and efficient way to free up space in your mailbox while having the flexibility to access and collaborate on your files conveniently.

Optimize Attachment Sizes

Attachments can quickly fill up your Office 365 mailbox, resulting in limited storage space. To maximize your mailbox size and optimize attachment sizes, follow these tips:

1. Use cloud storage: Instead of sending large attachments through email, consider using cloud storage services like OneDrive or SharePoint. Upload your files to the cloud and share the link with the recipients. This way, you can avoid clogging up your mailbox and ensure that the attachments are accessible even after a long period of time.

2. Compress files: If you must send attachments via email, compress the files to reduce their size. Many file compression tools are available that can significantly decrease the size of large files without compromising their quality. By compressing files, you can send and receive attachments more efficiently.

3. Convert files to PDF: Convert larger files to PDF format before sending them as attachments. PDF files are generally smaller in size compared to other file formats like Word or Excel. This can help reduce the overall size of the attachments and improve the storage efficiency of your mailbox.

4. Resize images: Images are often the main culprits of large attachment sizes. Before attaching images to an email, consider resizing them to a smaller resolution. This can significantly reduce the file size without significantly impacting the image quality. There are various image editing tools available that can help you resize images easily.

5. Delete unnecessary attachments: Regularly review your mailbox and delete any unnecessary attachments. Many times, we forget to delete attachments after they have served their purpose. By removing unnecessary attachments, you can free up space in your mailbox and make room for important emails and attachments.

By following these optimization techniques, you can effectively manage the size of your mailbox in Office 365 and ensure that you have enough storage space for your important emails and attachments.

Remove Unnecessary Emails

One of the most effective ways to increase your mailbox size in Office 365 is to remove unnecessary emails. Over time, your mailbox can become cluttered with outdated or irrelevant messages that you no longer need.

To begin, go through your mailbox and identify any emails that you can safely delete. This may include old newsletters, promotional emails, or messages that are no longer relevant to your work or personal life.

Before deleting any emails, make sure to check if there are any important attachments or information that you need to save. If there are, take the time to download or forward those items to yourself so that you can access them later.

Once you have identified the emails to delete, you can use the built-in tools in Office 365 to quickly and efficiently remove them from your mailbox. You can use features like search filters, sorting options, or the sweep tool to help you identify and delete groups of emails at once.

Remember, removing unnecessary emails not only helps you increase your mailbox size, but it also improves your email organization and makes it easier for you to find important messages in the future.

Tip: To prevent your mailbox from getting cluttered again in the future, consider setting up rules or filters to automatically sort incoming emails into different folders. This way, you can keep your inbox clean and focused on the most important messages.

Implement Email Quotas

One way to increase mailbox size in Office 365 is to implement email quotas. Email quotas allow you to set limits on the amount of storage space each user can consume in their mailbox. By setting quotas, you can ensure that users do not exceed the allocated storage space and help manage the overall storage usage in Office 365.

To implement email quotas in Office 365, follow these steps:

Login to the Office 365 admin center.
Go to the Exchange admin center.
Navigate to the Recipients tab and select the mailbox for which you want to set the quota.
Click on the Mailbox Usage section and then click on the More Options button.
Choose the Storage Quotas option.
In the Storage Quotas window, you can set the storage quota and warning level for the selected mailbox. The quota defines the maximum storage space that the mailbox can use, while the warning level notifies the user when they are nearing the quota.
Click on the Save button to apply the changes.

By implementing email quotas, you can effectively manage mailbox sizes in Office 365 and prevent users from exceeding their allocated storage space. This helps to optimize storage usage and ensure smooth operations in your organization.

Monitor and Track Mailbox Usage

In order to effectively manage and increase your mailbox size in Office 365, it is important to monitor and track mailbox usage. By doing so, you will have a better understanding of how your mailbox is being used and can take necessary steps to optimize it.

Here are some steps you can take to monitor and track mailbox usage:

Enable mailbox size limits: In Office 365, you can set mailbox size limits to control the amount of storage space each user has. By setting these limits, you can prevent users from exceeding their allocated storage and identify users who may need additional storage.
Regularly check mailbox size: You should regularly check the size of each mailbox to identify any unusually large mailboxes. By doing so, you can take necessary actions such as archiving or deleting old emails to free up space.
Use mailbox usage reports: Office 365 provides mailbox usage reports that give you insights into how storage space is being utilized. These reports can help you identify trends and patterns in mailbox usage and take necessary actions to optimize storage.
Implement retention policies: Retention policies can help manage mailbox size by automatically deleting or moving emails that are older than a certain timeframe. By implementing retention policies, you can ensure that your mailbox is regularly cleaned up and unnecessary data is removed.
Educate users: It is important to educate users about mailbox size limitations and best practices for managing their mailbox. By providing them with guidelines and tips on how to organize and manage their emails efficiently, you can help reduce the risk of mailbox size issues.
Monitor mailbox size growth: Keep track of the growth rate of your mailboxes to identify any sudden spikes in usage. This can help you proactively allocate additional storage or investigate any potential issues that may be causing the increase in mailbox size.

By regularly monitoring and tracking mailbox usage, you can effectively manage your mailbox size in Office 365 and ensure that users have enough storage space to meet their needs.

Enable Auto-Archive

If you are running out of mailbox space in Office 365, one effective way to increase your mailbox size is to enable the auto-archive feature. Auto-archive automatically moves older emails from your mailbox to an archive folder, freeing up space in your mailbox for new emails.

To enable auto-archive in Office 365, follow these steps:

Open Outlook and go to the File tab.
Click on Options, then choose Advanced.
Under the AutoArchive section, click on AutoArchive Settings.
Check the box next to “Run AutoArchive every…” and set the desired timeframe.
Choose the folder(s) you want to auto-archive from in the list.
Set any additional settings or exceptions as desired.
Click OK to save the changes.

Once auto-archive is enabled, Outlook will automatically move older emails to the archive folder based on the specified timeframe. You can access the archive folder at any time to view and search for these emails. Keep in mind that archived emails may take longer to retrieve since they are stored in a separate location.

Enabling auto-archive is a simple and effective way to increase your mailbox size in Office 365. By moving older emails to an archive folder, you can continue receiving and managing new emails without worrying about running out of storage space.

Use Personal Archives

If you have already reached the maximum mailbox size in Office 365 and need to increase it, one solution is to use personal archives. Personal archives provide additional storage space for your emails and other items, allowing you to keep important data without having to delete anything.

To use personal archives in Office 365, you need to enable the archiving feature for your mailbox. Here’s how you can do it:

Step 1: Access the Admin Center

Open your web browser and navigate to the Office 365 Admin Center.
Sign in with your administrator account.
Go to the Exchange admin center.

Step 2: Enable Archiving

In the Exchange admin center, go to the recipients tab.
Select the mailbox for which you want to enable archiving.
Click on the “…” button and choose “Enable Archive”.
Follow the instructions to complete the archiving setup.

Once the archiving feature is enabled for your mailbox, you will have access to additional storage space in the form of a personal archive. You can move old emails and other items to the archive to free up space in your mailbox.

To access your personal archive in Office 365, simply click on the “Archive” folder in Outlook or Outlook on the web. You can search, browse, and retrieve items from your archive just like you would with your regular mailbox.

Using personal archives is a convenient way to increase the mailbox size in Office 365 without having to delete important data. It provides a secure and easily accessible storage solution for your archived items.

Request a Mailbox Size Increase

If you are using Office 365 and need to increase the size of your mailbox, you can easily request for an increase. Increasing your mailbox size allows you to store more emails and attachments, providing you with additional storage space for your important files and communications.
