Here are some steps you can take to troubleshoot Outlook freezing when using Exchange:
- Check your Outlook version. Make sure you are running the latest version of Outlook by checking Microsoft's website.
- Disable add-ins. If you have third-party add-ins installed in Outlook, disable them to see if it resolves the issue.
- Run Outlook in safe mode. To open Outlook in Safe Mode, press and hold the CTRL key while clicking the Outlook.exe icon.
- Repair your Outlook profile. Using the Mail applet in the Control Panel, delete your current Outlook profile and then create a new one.
- Uninstall and reinstall Outlook. If all else fails, uninstall Outlook from your PC and then reinstall again.
