Hi Folks,
we are working on a cross forest migration for AD and Exchange, where Source Exchange is 2010 SP3 and Target new Exchange is 2013 CU8. while migrating the mailboxes we are getting the below issues and it takes ages to complete. i have migrated one mailbox earlier with 4.7 GB size it after lots of retries it took 28 hours to complete.
below is another mailbox which is quite smaller in size to check but i am still getting the same problem. what could be the cause for this. i have done all custom settings for MRS proxy and client binding at source Exchange server, but the results are still the same.
Informational: The request has been temporarily postponed because the mailbox is locked. The Microsoft Exchange Mailbox Replication service will attempt to continue processing the request after 6/19/2015 2:40:07 PM.
