I also have such problems.. Zimbra 6.0.0 GA, Outlook 2007 with XP professional...
When I do e.g. searches or delete 20 mails at one time, then outlook uses 99% CPU all the time. If I close outlook then, it corrupts the ZDB.. after restart of outlook, it seems to repair the ZDB (cpu high), but never comes to an end..
The only thing that helps is deleting the ZDB file and resync.
For me, it seems to happen only when opening a second mailbox.. |
