Cannot get updating of address book entries to sync properly, seems to cause the IMAP folder index to corrupt, automatic compaction of folder on address book update, very much a waste of time. Too touchy I'm giving up. I have a business to run.

Down grading review as auto sync doesn't really seem to work. Updates in adderss book cause new IMAP entry, delete seems ok when only one computer is invovled but these are not noticed by address books on other machines.

The initial sync put all the contacts in the designated IMAP folder. The auto sync is quick as well.
Currently have SyncKolb on three machines and the initial syncing is ok but you get duplicates

As you sync each separate address book, you will get duplicates and the initial sync does not make any effort to flag duplicates based on any criteria including an email address and no criteria can be defined. The de-duping must be done manually. I suppose these entries could be exported, sorted to squeeze out the duplicates. In any case, the auto sync makes removing duplicates more complicated as additional computers with their own address books with their own unqiue entries are added.

A mechanism to define how to match entries so as to avoid duplicates ought to be provided, maybe I'm missing something.

Notes:
You should create a new IMAP folder to hold the sync'd contacts. Otherwise, the contact entries, which act like emails, will intermix with other emails in the folder, clogging the folder with things you otherwise won't want to view.

I've only done Address book entries and not tasks or calendars.
