This doesn't have a lot to do with Cyrus, I'll admit (I am a big big fan of cyrus, though). But I need to come up with some kind of answer in order to make management even consider migrating away from exchange.
Cyrus has public folders, which is good. But when using Outlook against an IMAP server, you can't store contact folders on the IMAP server. What have people used in the past as a solution for having a public contacts folder in Outlook shared throughout an organization when not using an exchange server? Do you mount it from a share or something?
