I run 100+ domains on ZCS server and it's running fine. Only problems I have are users with mailboxes over 2 GB in size which are using Outlook via IMAP. Problems involve several Outlook timeouts, neverending syncing, very slow changing view from one folder to another etc.
It is very hard to determine the REAL cause of al causes, which could be guilty for all problems, and it seems it's connectivity in general in one case, and too large mailbox in another case, then Outlook 2003 in third case...and so on.
But all problems have Outlook of any version in common.
So I am thinking about trying with Outlook connector. But since it's production server, I'd like to hear what experienced users and admins have to say about Outlook Connector:
- performace vise, how is it compared to IMAP? Faster, better?
- regarding endless sync problems with IMAP, is Outlook Connector designed better, for example to not sync everything all the time, or to optimise syncing in order to not cause problems with multi GigaByte mailboxes?
