Steven_F_603 I was able to resolve by removing the problematic Windows update as per https://blog.lan-tech.ca/2020/07/15/outlook-fails-to-start/

RobWill_19 I don't have this update to uninstall and I still have the same problem as the others. I did reinstall all Microsoft products and can only open Outlook in Safe Mode. Thanks.

  DebarahWilson You can try the version rollback as suggested in this thread or as in the "Update" note on the blog article I referenced there is a fix being pushed out and you may just have to close and re-open Outlook.
