We are trying to move our system mailbox SystemMailbox{e0dc1c29-89c3-4034-b678-e6c29d823ed9} from 2010 to 2013 so we can do ediscovery searches on 2013.  The move fails because it exceeded the max number of corrupted items.  Are there any issues using the -AcceptLargeDataLoss when moving this mailbox?  Thanks

That should be ok. If the items are corrupt, then they are no good to anyone regardless!

Thanks, that's kind of what we were thinking too.  If I understand correctly, worst case we could delete the mailbox but leave the AD object and create a new mailbox for it, I think?

If you needed to recreate:

Note you can also create more than one Discovery Mailbox as well.

Thanks, the move went ok, and no issues.  :)
