I have noticed that reoccurring events that I delete one of on my blackberry is not syncing back to Zimbra. Normal events delete fine. Also when I read an email in Zimbra, it is taking up to 15-20 minutes to show as read on the blackberry. Even if several new email/calendar items come in and are synced to the blackberry instantly. Just the read status is slow. Does anyone have any insight on those issues?
