Cross-tenant mailbox migration in now in Public Preview

Thanks Kiran2150 : did the trick for us !

We now run into a weird situation.

I created a test MailboxUser on source tenant, prepared a MailUser accordingly on the federated target tenant.

I just sent and received a couple of mails, added an appointment and sent an invitation to populate the mailbox a bit.

When I launch the cross-tenant migration for that user, I run in the following error :

Error: MigrationPermanentException: Source mailbox 'Tests TECHNIQUES' contains unsupported mailbox location(s) - ComponentShared. Cross tenant moves support only moving Primary mailbox, or Primary + Archive mailbox. Please remove unsupported mailbox location(s) and try again. --> Source mailbox 'Tests TECHNIQUES' contains unsupported mailbox location(s) - ComponentShared. Cross tenant moves support only moving Primary mailbox, or Primary + Archive mailbox. Please remove unsupported mailbox location(s) and try again.

It basically states that the source Mailbox containe one or multiple ComponentShared mailbox locations and that those cannot be moved within a cross-tenant migration.

Problem is this Mailbox only have one primary location and no ComponentShared one :

MailboxLocations                          : {1;7f6f523c-c8ac-4321-b964-c56e46bd1876;Primary;FRAP264.PROD.OUTLOOK.COM;d5d70b4e-d1af-4a55-9550-763722395a2b}

I tried to run the migration batch with option -PrimaryOnly but it fails stating a parameter issue.

Does anybody have any idea what I could try now ? I've jumped in so many hoops to get that far and now I feel really clueless and don't know where to go from there...
