Frequently Asked Questions

Why can the administrator see all calendar events but staff cannot?

This discrepancy is usually caused by insufficient read permissions assigned to the staff, or a synchronization bug affecting the local Outlook desktop clients of the staff members while the administrator's client is functioning normally.

Will enabling 'Shared Calendar Improvements' delete any existing events?

No, enabling this feature simply changes the protocol Outlook uses to sync shared calendars from the Exchange server. It does not delete or alter any existing events.

How do I check if there is a Microsoft 365 service outage affecting calendars?

If you are an administrator, you can log in to the Microsoft 365 admin center, navigate to 'Health', and click on 'Service health' to view active incidents affecting Exchange Online or shared calendars.
