Outlook 365 not opening in Windows 11

I noticed that Outlook did not open automatically in Windows 11 like it should when I rebooted, so I tried to start it manually. That didn't work either. Not even running "outlook /safe" worked.

Am I missing something here?

    When I try to open Outlook from the 365 left side toolbar I get various warnings, the first says:

    "Outlook cannot log you in. Verify you are connected to the network and are using the proper server and mailbox name. The Microsoft Exchange Information Service is missing required information. Modify your profile to ensure you are using the correct Microsoft Exchange Information Service."

    MIcrosoft Outlook does not appear in my Application List. I am at a loss.

    Hoping someone can help.

    make sure you put a space after "outlook" before the /. Ex: outlook /safe

    Hi Owen,

    This was advice I was given about a year ago. It works but isn't a permanent solution - mine continues to fail every 3 or 4 months, so I have to go through the process again. It's a pain in the backside and after so many posts about the problem, ever since Windows 11 was introduced, I can't understand why Microsoft haven't fixed the problem ... after all they created it!

    Anyway, rant over, here's the solution, I was given ...

    1. Open Control Panel - Programs and Features
    2. Select Microsoft Office in the application list
    3. Right click and click 'Change'
    4. Click 'Repair' then select Online Repair

    Good luck,

    Bill Middleton
