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?

    I currently having a problem with Outlook and Xfinity where I constantly get pop up wanting my password for imap.xfinity.net. I know my password is correct as it works on my Iphone and when I logon to email at Xfinity.com. I have allow third party email checked correctly on Xfinity website. I have done "repair" and other suggestions. Still can't receive email in Outlook

    This also worked for me. But in Windows 11 you will need to

    (1) get to APPS via the Control Panel as stated, click on "Installed apps",

    (2) then look for "Microsoft 365", and click on the three dots "..." to the right.

    (4) Now select "Modify"

    (5) then select "On Line repair"

    (6) wait for the repair to complete,

    The first time I tried to open Outlook after the repair I got an error message, when I tried again it worked.

    Good luck!

    Thanks Mark,

    The quick repair option worked for me in this instance and I would suggest try this first before going down the longer online route. Top tip though chap. Thanks.

    Hello, it seems that I cannot open Outlook in safe mode. As soon as I click ok on the run button, I get a Windows security box that opens asking for my Outlook credentials. I am trying to connect with an Exchange server at work. I have successfully connected for years and then just started having problems. I am running Windows 11 on a one year old PC.

    *I type in the credentials (just the password, the username is already there)

    *The box disappears and then immediately comes back asking for log in credentials again

    *I have entered log in credentials several times, finally hit "Cancel"

    *A box pops up with the following:

    Cannot start Microsoft Outlook. Cannot open the Outlook window. The set of folders cannot be opened. You must connect to Microsoft Exchange with the current profile before you can synchronize your folders with your Outlook data file (.ost).

    *I have uninstalled and reinstalled Microsoft Office365 three times. The installation says that it is fine and all of the MS apps open without issue except Outlook. When the MS apps first open the same box asking for the password comes up but goes away without incident and the app opens.

    Thanks. Joe
