I second the sentiment, it’s unbelievably annoying. Even more so when the suggested solution from the “support” appears to be “You can downgrade to a version before we introduced this bug”. I’m not even gonna try switching to that new crapware, I’m just going to change client altogether.
Thanks for the tip, instead of enduring any longer, i decided to downgrade, which was easier than I expected, and this old version works, doesn't have this bug.
Just delete the Outlook app from the Applications folder, and run the Outlook installer from version 16.109.3 (June 02, 2026) [1]. All data is there, no need for any backups or anything.
Then, delete (or rename) the Microsoft AutoUpdate App, which lives in: /Library/Application Support/Microsoft/MAU2.0
