I have deployed 2 pilots for coexistence with Exchange 2007 and 1 Production environment in progress. I have the following problems:
1. In production environment, once mailboxes are moved from Exchange 2007 to Exchange 2013, outlook 2007 clients cannot connect and always keep asking password (same behaviour that I had on coexistence from ex2007 and ex2013 RTM). In pilot environments I don't have this problem. Configuration of Outlook Anywhere and Autodiscovery as well as Virtual Directories and Certificates are identical and they are done according documentation with CU1.
2. Once mailboxes are moved from Exchange 2007 to Exchange 2013, mailboxes cannot be moved back to Exchange 2007. The migration task starts and then shows "total mailbox 0, synced 0, finalized 0, failed 0" and no error in return.
Any ideas?
