Navigate to Privacy Settings

Go to the 'Privacy and security' section in the left sidebar and click on 'Clear browsing data'.

Restart and Test

Close your browser completely, reopen it, sign back into Outlook on the web, and attempt to save your email template again.

Template Size Limit: The 'My Templates' app in Outlook has a strict total size limit of 32 KB for all combined templates. Ensure you are not exceeding this limit before attempting to save.

Review Official Microsoft Exchange Guidance

Frequently Asked Questions

Why do my deleted email templates keep reappearing in Outlook?

This usually happens due to a synchronization issue between your browser cache and the Microsoft Exchange backend server. Clearing your browser data or checking for server-side syncing errors can typically resolve this.

Is there a size limit for templates in Outlook's My Templates add-in?

Yes, the total size of all templates saved in the 'My Templates' app cannot exceed 32 KB. If you exceed this storage limit, Outlook will display an error and prevent new templates from saving.

Can I fix this Exchange backend issue by myself?

If clearing your cache and removing excess templates does not work, you cannot fix backend Exchange issues alone. You must contact your organization's IT administrator to submit a service request to Microsoft.
