Since Zimbra pre-version 5 does not have Private capability at the meeting level we've done all of these options:
- Delete "Private" Activities / To-Dos before they are inserted (clean, easy to understand, infuriating for some users)
- Pre-pend "PRIVATE:" to the relevant activities (easy to find and the user can deal with them as they will)
- Separate the "Private" items into a separate database and insert into separate calendars. A little time-consuming all around, but it worked this weekend at a migration in Pennsylvania.
In Zimbra 5 this all becomes moot -- but we want to make sure current clients contemplating a Zimbra migration know their options.
