Understanding the problem

When using Office 365, many users encounter an issue with sending emails from an alias. The problem is that the send as alias function is not working as expected. This can be frustrating and confusing, especially when you rely on your aliases for different purposes.

Office 365 allows you to create aliases, which are alternative email addresses associated with your primary account. These aliases can be used for various purposes, such as sending emails from a different name or department within your organization. However, when the send as alias feature is not functioning correctly, it prevents you from sending emails using your desired alias.

This issue can have several causes. One possible reason is that the send as alias feature needs to be enabled by your Office 365 administrator. Sometimes, this feature is not enabled by default, and you need to request it to be enabled for your account. Another potential cause is incorrect configuration settings or outdated software, which can lead to conflicts and compatibility issues.

Common symptoms of the problem:

When trying to send an email, the send as alias option is not available in the “From” field.
The email appears to be sent from your primary email address instead of the desired alias.
Recipients may receive emails from your primary email address instead of the alias, causing confusion or misunderstandings.

To troubleshoot this issue, it is essential to check the settings and configuration of your Office 365 account. It may also be necessary to consult with your Office 365 administrator for assistance. By understanding the problem and its possible causes, you can take the necessary steps to resolve the send as alias not working issue in Office 365.

Note: The steps to fix this issue may vary depending on your specific Office 365 configuration and permissions.

Common causes for send as alias not working

When using Office 365, there are several common causes for the “send as alias not working” issue. Understanding these causes can help you troubleshoot and resolve the problem more effectively.

Therefore, it is advisable to consult with your IT department or Microsoft support before disabling any add-ins or extensions, especially if they are critical for your work.

Checking firewall and security settings

If the send as alias is not working in Office 365, it is important to ensure that the necessary firewall and security settings are properly configured. Incorrect firewall or security settings can prevent the sending of emails using a specific alias.

Here are some steps to check the firewall and security settings:

Review firewall settings: Verify that the necessary ports and protocols for email communication are open in the firewall. This includes ports for SMTP (Simple Mail Transfer Protocol) and any other email-related protocols that Office 365 uses.
Check security software: Make sure that any security software or firewall programs installed on the computer or network are not blocking outgoing email traffic. Temporarily disabling the software or adding an exception for Office 365 can help identify if this is the cause of the issue.
Verify DNS settings: Ensure that the domain’s DNS (Domain Name System) records are correctly configured, particularly the MX (Mail Exchanger) records. Incorrect DNS settings can cause issues with email delivery, including sending from aliases.
Review Office 365 settings: Double-check the Office 365 configuration settings to confirm that the alias is set up correctly. This includes verifying that the alias has been added and assigned the necessary permissions to send emails.

By following these steps and ensuring the correct firewall and security settings are in place, the issue with the send as alias not working in Office 365 should be resolved, allowing users to send emails using their desired aliases successfully.
