Migration of a Microsoft Bookings Scheduled Mailbox using ODM is not supported (4266127)

When using On Demand Migration (ODM) to migrate a Scheduled Mailbox account to the target tenant, the following error is logged:

Unexpected exception while loading properties for items(The type of the object in the store (Booking) does not match that of the local object (CalendarItem).)

If the Scheduling Mailbox is manually created on the target and the accounts are mapped within ODM, the following errors are logged when the migration occurs:

Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index

Note: Migrating an empty Scheduled Mailbox produces no errors.

WORKAROUND
No workaround at this time.
