We were on 4.5.0, but upgraded to 4.5.6 last night.
It appears that the SUMMARY=EMPTY is a problem with some of the entries. Fixing it enabled the import to succeed.
We've also noticed that every instance of ATTENDEE;CN needs to be replaced with ATTENDEE;RSVP=FALSE, as these are entries where the user hasn't RSVP'd to an appointment yet, and Zimbra doesn't seem to like these on the import without specifying the RSVP status.
Not sure if that's a bug that was noticed and fixed already, though.
Cheers! |
