I just tried to update my dell desktop to Office 365, and now when i try to open Outlook, it immediately shuts down. clicking the outlook icon brings up https://outlook.live.com/mail/inbox but i don't want that. I want my traditional outlook. Help?

in the "Type here to search" box on the Task Bar type > cmd   >choose run as an administrator.. paste the commands into Command Prompt box.

Hit the enter key on the keyboard after pasting each command line.

cd "C:\Program Files\Common Files\microsoft shared\ClickToRun"

and then

officec2rclient.exe /update user updatetoversion=16.0.12827.20470

UPDATE:

Do nothing, wait.   See:

Microsoft is automatically propagating a fix.....  I am seeing it automatically patch some of my clients i had not fixed yet, that complained earlier..

    The Outlook 365 Problem was fixed here after a simple reboot

    at 5 pm EST

    Apparently MSFT pushed out the promised patch.

    One question remains:

    I read the temporary suggested Outlook rollback solutions

    One problem:

    there is no "ClickToRun" in my C:\Program Files\Common Files\microsoft shared

    (Outlook 365 on Win10)

    Any suggestions how this is possible?

    (- as it makes it impossible to roll back Outlook)

    Today, I was experiencing the same issue. Outlook would open and 5-10 seconds later it would close. I ran a cleaner and several restarts but could not seem to fix the issue. I attempted a repair through the Program uninstall/change option within control panel but this seemed to have no effect.

    Later I cam across someone else's suggestion to uninstall the latest update. Upon going into Settings and to the Windows Update section I could see that there was a pending install for a an update. I just waited until it was complete, restarted the computer and let the updates fully install.

    After this, Outlook has not had any issues.

    The updates installed today are: KB4565633, KB4497165, and KB4565483.

    Hope this provides someone a little help.
