I too am experiencing this problem. When in Outlook, all functions of Outlook work properly EXCEPT when in CONTACTS. When I open Contacts, the BOX typically on the R half of the screen that contains all of the contacts information and notes now appears hovering on the left half of the screen, covering over the alphabetical contact list . There is no way to move it, rendering the program unusable. I believe that this may be the result of a recent WINDOWs update within the past 10 days. (Windows 11 seems to have updates every other day.) Or possibly an Outlook update (today is Oct 4). I went into File/Office Account to check for available OUTLOOK updates. The worse of it is that if you attempt to go into the box to retrieve information on the notes - it deletes the contact!!!! I have Office Home & Business 2016 auto updated to 2021. Windows 10 auto updated to Windows 11.
I am hopeful that WINDOWS or OUTLOOK has an update to auto correct soon!
