Since mid-last week, I have issue with my Outlook whee ZCO (5.0.18) seems cannot do a full resync and got some strange result. Noted that this issue happen on both my laptop and workstation, so it may be server issue rather than ZCO issue.
While the first notable sign is that the web gui become very slow (sometimes even timeout with server slow message) when Outlook is running. Shutdown Outlook and web gui was back to normal. From that point on, ZCO report sync failed with a number of calender create failed warning, and web gui continue to be slow whenever Outlook was running.
As it no long sync at all, I have blow away *.zdb and it's still the same right away (aka no sync but can pick up new message, web gui slow when Outlook runs). Then, I have uninstall ZCO, remove profile complete and reinstall. It can sync for around half an hour and get into the same issue again.
As it got some warning about Calendar, I then try to access calendar directly and the url link will result in 403 error (normal, it will prompt for calendar download). I've also noted that whenever the web gui pop up with an reminder, it will white out (using firefox) for a few minutes. So, seems like it's very slow.
I've check with others and seems like I am the only one having this problem. I've tried to migrate my account to another Zimbra mail store and problem follows. I am running out of idea here. Anyone else experience the same? or aware of any fix? Or, is there any way I can found out what happen?
