Hi, Since my old email server is old, so, I changed to a new email server. Both are running isp 3.0.3.2. some of my clients will keep emails on server even the downloaded emails to their outlook. The problem I not face to is, the server move successfully. All clients old emails also moved to the new server, but their outlook will download all old emails again evev I manually marked the emails as read in server. It really make me and my clients crazy because some of them keep years of emails. How can I solve it? Thanks!!
I think you should have moved emails with imapsync because imapsync preserves all flags: http://www.howtoforge.com/how-to-migrate-mailboxes-between-imap-servers-with-imapsync
