I don't know what happened, but just the middle of last week, my ZCO began to experience massive slowdowns in Outlook 2007 performance. The slowdowns are mostly prominent when selecting the different mail folders within the Zimbra account and when switching from email to calender mode - etc... I had tried to delete the entire Zimbra profile and recreate it from scratch, but the same sluggish performance occurs. Wierdly, it was working just fine earlier in the week and no software was changed... Any clue on what is going on?
Current ZCO is 5.0.8.
