Outlook app will not open on any of my computers

If the Outlook app is not opening on any of your computers, it could be due to several reasons, including compatibility issues or corrupted settings. Here are some steps you can take to troubleshoot the issue:

1. Check Compatibility Mode: Ensure that Outlook is not running in compatibility mode. You can do this by locating the Outlook.exe file, right-clicking it, selecting Properties, and then checking the Compatibility tab. Make sure the Run this program in compatibility mode for option is unchecked.
2. Repair Office: You can try repairing your Office installation. Go to Control Panel > Programs > Programs and Features, select your Office installation, and choose Change. Then select Repair.
3. Create a New Profile: Sometimes, the Outlook profile may be corrupted. You can create a new profile by going to Control Panel > Mail > Show Profiles > Add. Set up the new profile and see if that resolves the issue.
4. Check for Updates: Ensure that your Office applications are up to date. Sometimes, updates can fix bugs that may prevent applications from opening.
5. Disable Add-ins: If Outlook opens in safe mode but not normally, an add-in might be causing the issue. You can disable add-ins by going to File > Options > Add-ins, and then manage COM Add-ins by clicking Go. Uncheck any add-ins and restart Outlook.

If these steps do not resolve the issue, you may need to look into more specific error messages or logs that could provide further insight into the problem.

Hi Robert,

I assume that you cannot open the new Outlook app, is that correct?
