Authentication prompt repeately popup Outlook for Mac 16.67 (22101000)

Copper Contributor



I'm running Outlook for Mac 16.67 (22101000) and I keep getting the authentication window for my MS 365 all the time.


One account using Okta authentication has the authentication popup every 2 minutes, this one closes automatically.


Another account, which uses external authentication, is unable to log in at all.


Any idea/help on this one?
