Keep getting the same error for different shared mailbox for multiple users
Environment - Exchnage Hybrid
users are migrated to cloud - all cloud now (remote mailboxes on premise)
shared mailboxes/calendars - hybrid (rmeoe mailboxes on-premises)
Issue is not happening in OWA, only Outlook Desktop
Office suite is updated to latest version
Profiel reconfigure has been done - not helped
permissions rmeoved for delegates and calendar , but issue still persists
Error happens only when modifying an existing event in Calendar of a Shared Mailbox by a delegate
Need suggestions from whoever has seen this before and from Outlook MVP's / Product Group Team.
