How do I delete Microsoft 365 history?

To delete your Microsoft 365 search history, follow these steps:

1. Sign in to Outlook using your Personal account or Work or school account.
2. At the top of the Outlook page, select Settings (usually a gear icon).
3. Select General, and then Privacy and data.
4. To delete your search history, select Delete history. You also have the option to export your search history to a .csv file by selecting Export.

This process clears your search history within the Outlook web application. Keep in mind that this won't necessarily delete your entire Microsoft 365 activity history, which might be stored in other Microsoft services. Deleting history in other Microsoft 365 apps might require different steps.
