I have:
- Exchange 2010 SP3 RU4 on Windows Server 2008 SP2;
- Exchange 2013 SP1 on WIndows Server 2012 R2.
All connections occurs to Exchange 2013 server. Everything is OK until some user mailbox moved from Exchange 2010 database to Exchange 2013. When it occurs, this user automatically switched to OWA 2013, it working, SMTP working, but IMAP and POP not working. All e-mail clients say "Username or password incorrect". We try to use DOMAIN\username, username@DOMAIN, bare username, user mailbox as username. All without result.
IMAP on port 143, POP on port 110.
