I've used Zimbra Desktop for a couple of years now.

Version 7.2.1 (GA (build 11637)) is the latest one I've installed. It's been working fine for a very long time. All of a sudden one of the accounts (quite large) is having problems synching. We are several colleagues having set the account up in Zimbra Desktop. The others don't have a problem with it. It's only me.

Our setting are the same.

I've tried removing account and adding account.
I've tried uninstalling Zimbra Desktop and installing it again.
I've tried reindexing.

Please help. It's very annoying having to use webmail for only this account and Zimbra Desktop for my 4 other accounts.

I don't get any errormessages. The account has a symbol for synching, which it does for ages, and then the icon switches to a red square.

Kind regards,
