We're considering migrating from Exchange to Zimbra and had a question about calendaring.

We do a lot of shared calendering, we have sales and admin folks who manage the calendars of others, adding/deleting meetings, etc. In Exchange we have a calendar-admins group which has full authority to manage everyone else's calendar.

Can Zimbra support this same level of functionality? Can we view each other's calendars as well?

Also, are there any caveats for Mac clients versus windows clients or do they work equally as well?

Thanks in advance!
