Migrate OME mailbox between tenants

Hi,

I need to migrate a couple of mailboxes between two Office 365 tenants. The source tenant uses OME (Office 365 Message Encryption) which complicates things. I need to remove the encyption before importing to the target tenant. Any advice?

Thanks!

I'm not aware of any products that decrypt messages as part of the migration process, but it's certainly doable via the API or PowerShell. I know TonyRedmond will love this thread :)

    TonyRedmond Thank you!
    
    The solution is to export to .pst and use Powershell to decrypt (via Unprotect-RMSFile)
