Has any of you seen a situation before where the Create event in Exchange Calendar for office 365 and SP 2016, creates the event successfully for some users and failing for only 2-3 users? The permissions are looking OK, the action is taking the credentials for an exchange admin account and the workflow is running fine and successful to the end. But the event doesn't show up on the calendars of "some" users.
I'm not getting any error messages. It is failing silently.
The workflow shows that the event was created, all nice and green. Log says it was created successfully.. we open the calendar, nothing in there. We thought at first that it might happen if the spot was already busy/booked, but no, it is also failing on empty calendars.
