Teams calendar for exchange on prem users not working
Hello I am having issues to make Exchange On prem users use Calendar on teams. Initially Client autodiscover was blocked externally but they added a cname and open flows but I am still having is...
For Teams to show calendars, the user must have an Exchange Online mailbox or be in a properly configured Exchange Hybrid with OAuth / Modern Auth working. Is that the configuration you're using?
You can do a quick test to see if things are configured correctly by running the following command (replace the placeholder user with your own user account):
Test-OAuthConnectivity -Service EWS -TargetUri https://outlook.office365.com/EWS/Exchange.asmx -Mailbox email address removed for privacy reasons
