Hi,
I am busy with a migration of mailboxes from Exchange 2003 to Exchange 2013. I have migrated all the mailboxes from Exchange 2003 to 2010 and then uninstalled the Exchange 2003 server. I am currently migrating from Exchange 2010 to Exchange 2013 and I am experiencing some problems that I have not seen before.
I migrated a few small mailboxes, the in progress time show as 4.5 hrs. The migration completed with errors. I have had a look at the report and the error is as follows:
"Warning: Failed to set RehomeRequest on some of the requests related to the mailbox after the move. Error details: Too many cleanup retries, giving up."
Please can someone assist in resolving this, I have no idea where to look now.
