Using older versions of Outlook for Mac for personal email and calendar
Hi!
Do you have a Microsoft 365 subscription or a perpetual Office license?
Outlook Legacy is currently unlicensed and has switched to read-only/offline mode. Also, support for Legacy ends this month. If you are using the Outlook for Mac app (New Outlook) in Legacy Mode, try turning it off to revert to the original interface.
If that doesn't work, try reinstalling it:
- Right-click the Outlook app icon > Move to Trash > Wait for uninstallation to complete > Restart macOS.
- Install Outlook from the Apple Store.
