My company enabled 2FA last night and this morning I went to launch the Outlook 365 Desktop Application for Windows 10 and it never loads the window asking me to log in. It just stays blank and (not responding).
I have actually let this window stay open for 2+ hours. I have rebooted the machine multiple times. I went into Credential Manager and removed everything related to Office and Outlook.
The only thing I have yet to really try is Uninstalling and Reinstalling the application, but I feel like that is not going to resolve the issue.
I was hoping someone had some suggestions or has run into this issue.
I opened up a couple of other Office applications on my computers such as One Note and Teams. Both of these apps required me to log in and use 2FA. Once I logged in to both of those apps I decided to try and re-launch Outlook and it did NOT prompt me to log in. (I don't know if that is a good or bad thing.) I was able to open Outlook and use it so I am happy.
