When I upgrade from 7.0 from 6.2.3, I'm unable to log in to send and receive mail from my IMAP server. If I try to revert back to 6.2.3 while 7.0 is still installed on the system, 6.2.3 no longer can log into my SMTP server.
To resolve, I have to remove all instances of 7.0 and 6.2.3 then reinstall 6.2.3. Can someone help me understand why 7.0 does not transfer my profile properly?
