One of our clients is reporting an issue with users of Vista Business Edition. After doing some packet analysis he determined that the traffic was releated to Outlook (and therefore the Zimbra connector). Are there any known issues with the Zimbra connector and Vista Business that would cause these kinds of symptoms?
The Zimbra server is running Version 4.5.9_GA_1455.RHEL4 16-Oct-2007
This happens ONLY on Vista Business. Other users on XP are doing just fine. Web client causes no such traffic problems either. We can also eliminate the clients network, because one of their users had the same issue when he took his laptop home. His home network died a death too!
