Outlook classic gets stuck while loading

For classic Outlook stuck at Loading profile, use this order:

1. Close Outlook completely.
2. End any Office processes in Task Manager if they are still running.
   • Right-click the taskbar > Task Manager
   • On Processes, locate Office processes and choose End task for each one
3. Start Outlook in safe mode:
   • Press Start and type Outlook.exe /safe, then press Enter
   • If Outlook opens in safe mode, close it and open it normally
4. If it still fails, disable add-ins:
   • In Outlook, go to the COM Add-ins list
   • Clear the check boxes to disable add-ins, then restart Outlook
   • Do not choose Remove. That can delete an add-in if administrative rights are available.
5. Create a new Outlook profile:
   • Close Outlook
   • Open Control Panel > User Accounts > Mail > Show Profiles
   • Select Add, create the new profile, then choose Prompt for a profile to be used
   • Start Outlook and select the new profile
6. Repair Outlook data files with the Inbox Repair Tool (scanpst.exe).
7. Repair Office. Try a quick repair first, then online repair if needed.

Because Outlook on the web is also missing recent mail and sent items, this is not just a local Outlook profile symptom. Classic Outlook can use a local cached mailbox, while web-based Outlook depends on the server-side mailbox view. If Outlook on the web is not showing current Inbox or Sent content, try these web-side checks:

1. In Outlook on the web, go to Settings > Mail > Layout and turn off Focused Inbox.
2. Review Rules, Conditional Formatting, or Sweep settings and temporarily disable them.
3. Change the Reading Pane position and set sorting to Newest on top.
4. Test Outlook on the web in an incognito/private browser window.

If classic Outlook still hangs and Outlook on the web still does not show current messages after these steps, run the Classic Outlook startup or connectivity troubleshooters in Get Help. If that does not resolve it, use contact support.
