We just installed SP1 on our Exchange 2007 environment. We still have a 2003 backend mailbox server where most of our users are still located. After the upgrade, IMAP and POP broke. I looked everywhere for documentation on what changed during the SP1 upgrade for these two new tabs (imap and pop) but couldn't find anything. I finally realized that IMAP and POP security settings had been changed/elevated. I had to change it from Secure TLS to Windows Integrated Authentication for both protocols so users could again connect with their client settings. The certificate had also changed so users were getting SSL errors - not sure why it pulled a different cert. IMAP and POP were working fine until the SP1. Some better documentation would have been nice. Also, when you upgrade the cluster service for CCR, it takes awhile. Plan for 20-30 minutes downtime when you upgrade your mailbox servers in CCR cluster.
