Migrating Shared Calendars to Microsoft 365

In order to migrate Shared Calendars to Microsoft 365, you need to use Auto-Discovery.

Unfortunately, you cannot set this if you specify your Plan (in Destination Settings) as either Office 365 or Office 365 Germany. You need to set the Plan type as Custom. It is also imperative that the Direct Exchange EWS URL setting is left blank as this will stop email notification from being sent.
