How to Automatically Delete Microsoft 365 Mail After a Set Number of Days
Question details
The user needs guidance on configuring Microsoft 365 retention policies to automatically delete mailbox data after a specified period, such as one day.
- Product
- Microsoft 365
- Device & OS
- not provided
- Scenario
- Automating the deletion of emails to comply with data retention rules or to manage mailbox storage limits.
- Observed behavior
- The user requires tenant administrative capabilities to configure, apply, and review automated email retention and deletion policies.
Ensure you have global administrator or compliance administrator credentials for your Microsoft 365 tenant, as configuring or troubleshooting retention policies requires elevated administrative privileges.
Create a Service Request in Microsoft 365 Admin Center
Because automated deletion involves tenant administration and policy processing, contacting Microsoft Support is the recommended way to review your retention configuration and processing status.
Setting up a policy to delete mailbox data after a very short period (like one day) requires careful configuration to ensure the Managed Folder Assistant processes the rules correctly without impacting compliance.
Sign in to the Microsoft 365 admin center using an account with global or support administrator permissions.
In the left-hand navigation menu, click on 'Support' and then select 'Service requests' or 'Help & support'.
Enter your request details, specifying that you need assistance configuring or troubleshooting a retention policy designed to automatically delete mailbox data after a set number of days.
Submit the request and ask the Microsoft 365 Support agent to review your current retention configuration, permissions, and policy processing status to ensure it runs correctly.

Frequently Asked Questions
Where are Microsoft 365 retention policies normally configured?
Administrators can create and manage retention policies in the Microsoft Purview compliance portal by navigating to Data lifecycle management and then selecting Microsoft 365.
How long does it take for a new email deletion policy to take effect?
Once a retention policy is applied to a mailbox, it can take up to 7 days for the Managed Folder Assistant to process the mailbox and start automatically deleting the emails.
Can individual users set up their own auto-delete rules for emails?
Yes, if an administrator has created and published personal retention tags to their mailboxes. Users can then apply these tags to specific folders or individual emails via Outlook on the web or the Outlook desktop app.
