I am setting up an IMAP account on my website's email, to use as webmail and on 2 laptops. As far as I can see, IMAP promises much but crucially fails to deliver. It does a great job syncing the emails in the three locations, but it is worse than useless having 3 separate address books all out of sync. The TB docs mention the SyncKolab add-on to sync the address books. But this is complex and frustrating. If it works at all, I can't puzzle out how. What syncKolab seems to do is to set up a new folder of the server called "contacts" and to place a message-form record in that folder for each address in the laptop address book. What good does that do me ...? Does this solve the problem in some way I'm not seeing? What I need is that the actual address book on the server contains the addresses on the laptops, and vice versa. I don't get it, how the server fold which Kolab creates, helps me. The server address book is not updated. I do not need calendar or task sync, just address book. With or without SyncKolab; indeed, with or without Thunderbird! how do I sync the address book on my IMAP server with my laptops? Many thanks Andy
