I'm trialing Zimbra and until now, it's been very problem-free.

Today, I was setting up a new user who uses two computers. I set up one (a Macintosh) without issue, and synchronized the calendar, with no entries. Then, I set up Outlook 2003 on XP with the Zimbra connector. Outlook had a large number of calendar entries.

After this initial calendar sync, Outlook now has no entries on the calendar!

How can I get these calendar entries back? Are they gone forever?
