Hi we have recently migrated to Exchange online from our on premesis solution. We are still in coexistence mode. the mailboxes that have been migrated to online are having issues listed below:
1. unable to share calendars.(100%)
2. unable to create meeting requests (35%).
3. unable to send emails on behalf of someone else.
4. Unable to view other users inbox.( they have the correct authorization to access it).
Any help will be highly appreciated.
