Migrate linked mailboxes to exchange online and teams
pazzoide76 ,
Late response for sure, and I'm not an expert in Teams, but all of the Exchange pieces in what you propose can/will work.
So yes, it is possible to implement full hybrid. Key to this is setting up Azure AD Connect properly by telling to sync both forests, that users appear more than once in the organization, and where it asks how to uniquely identify a user to match "ObjectSID and msExchMasterAccountSID/msRTCSIP-OriginatorSID attributes".
It is possible to migrate linked mailboxes. Assuming Azure AD Connect was set properly a linked mailbox will appear as a MailUser object in Exchange Online. If you see that you can migrate the mailbox.
Again, not an expert in Teams, but once you have a properly synced linked mailbox user you can enable them to use Teams and it should be fine.
