Using older versions of Outlook for Mac in business environments
One of our users has the exact same problem starting on the same day.
Gmail works fine, Mac Mail is fine. Moving the account to a new mac = same issue.
Create ne Outlook profile = same issue
Create new user on machine and then add gmail account = same issue
re-move and re-install office = same issue
reset Outlook preferences = same issue
Tested a PERSONAL Gmail account rather tthan my user's Workspace Gmail account works fine - wonderingif there is a difference between then in the way Outlook connects?
Rolling back to Office 2016 v 15.xx (released 2018) and the issue goes away. We are in the process of incrementally going back through the Outlook versions listed here: https://docs.microsoft.com/en-us/officeupdates/update-history-office-for-mac
So far none of the 16.xx versions work.
But were working just fine until April 20 @ 11:50 BST.
Issue is present on Big Sur and Catalina
Would be interested if a solution is found as we're just around in circles at the moment
Found the solution - it's really easy but a little obscure and I don't really understand WHY this fixed the issue...
In Outlook for Mac click Outlook > Preferences
Click Accounts
Delete the account by highlighting it and clicking the minus (-) sign
When prompted click "Delete from all devices"
Close and re-open Outlook
Re-add the account
Should all work now.
