Check Recipient’s Email Filters
If you’re experiencing issues with sending emails through Office 365, it’s possible that the problem lies with the recipient’s email filters. These filters are designed to block certain types of messages or send them to specific folders, such as the spam or junk folders.
When sending an email, it’s important to ensure that the content doesn’t trigger any spam filters. Avoid using excessive capitalization, special characters, or too many links in the email body, as these can be seen as spammy by the recipient’s email filters.
To troubleshoot this issue, ask the recipient to check their email filters and settings. They may need to whitelist your email address or mark your emails as “not spam” to ensure they reach their inbox. Additionally, advise them to check their spam or junk folders to see if your emails are being mistakenly filtered there.
Here are some steps the recipient can follow to check their email filters:
- Login to their email account
- Navigate to the settings or options menu
