Outlook for Mac - meeting cancellations stuck in outbox
Ash365 I have this issue as well, and it's happened to multiple people in my org. It persists after a full uninstall and reinstall of the product (though it appears that the issue subsided temporarily). My organization has observed this issue since April 9th, 2019, which leads me to believe it was present in the https://docs.microsoft.com/en-us/officeupdates/release-notes-office-for-mac#march-2019-release. Another member of our organization was running version 16.13 (Build 180513) and did not experience this issue.
I am not signed up for Office Insider and my org only runs stable releases. I am currently running Version 16.27 (Build 19071500).
Please let me know if you need any other information-- thank you!
Sounds like that you are having issues with sync and certificate..
Please try to downgrade to a earlier version of Office on your mac and see if that works?
