I have an Exchange 2003 server that's been running fine for the past nine months or so, and I decided to turn on IMAP/S and set up a new SMTP/S virtual server. It seems to work fine until there's more than one connection to the same mailbox. For example, if I leave my mail client open at home, I won't be able to retrieve my mail when I open it at work. Restarting IMAP4svc resolves the issue temporarily, but I have a couple of group mailboxes where multiple people would access the same account... so I can't spend my day restarting IMAP ;) Has anyone encountered this? Is there some setting that I've missed to allow multiple connections to the same inbox via IMAP?
