    Default Failure communicating with remote server. Please try again later.

    My Email server is IMAP on my home network and I can connect to it with a different email client. When I use Zimbra to try to connect it comes up with this error.

    I have tried changing passwords and starting and stopping both email server and client

    Default IMAP sync not working

    I have just installed Zimbra Desktop to my Windows Vista 32-bit and tried to set it up to read my IMAP mailboxes. It works partially but eventually says:

    Needless to say, reading the said Inbox via SSL-protected IMAP works flawlessly in Thunderbird. My "Inbox" is a pretty big e-mail set, though. The Inbox contains both e-mail messages and about 20 subfolders, some of which have subfolders. As far as I can tell, the sync has been able to fetch 626 messages in the main Inbox and all the subfolder names, but none of the subfolder contents. Additionally, it has not fetched any Inbox messages dated before Jan 6th 2007. I have a bunch of messages in there dating back to 2004.

    I've used scores of different e-mail programs since 80's. Since this is my first experience with Zimbra, I'm seriously not impressed.
