Hi Julien Schneider,

 

Can you try to restart Replication Service on Exchange ?

 

What are the logs saying ?

    Hi Nuno Silva,

      Hi Julien Schneider,

       

      You can see the logs where is the batch running. Is advised to run it on Office 365.

        Yes the batch is running on Office 365,

         

        Here is some logs of the batch :

         

        10.07.2018 12:58:35 [HE1P189MB0377] The Microsoft Exchange Mailbox Replication service 'HE1P189MB0377.EURP189.PROD.OUTLOOK.COM' (15.20.952.17 ServerCaps:FFFFFF, ProxyCaps:0FFFC7FD6DFDBF5FFFFFCB07FFFF, MailboxCaps:, legacyCaps:FFFFFF) is examining the request.

        Maybe the "CleanupOrphanedMailbox" is causing some trouble.

         

        For the moment, data transferred are still at 0 Byte after the restart of the replication service.
