Zimbra Free/Busy Calendar Scheduling

The Free/Busy feature allows users to view each other’s calendars for efficiently scheduling meetings. You can set up free/busy scheduling across ZCS and Microsoft Exchange servers.

ZCS can query the free/busy schedules of users on Microsoft Exchange 2003, 2007, or 2010 servers and also can propagate the free/busy schedules of ZCS users to the Exchange servers.

To set free/busy interoperability, the Exchange systems must be set up as described in the Exchange Setup Requirements section, and the ZCS Global Config, Domain, COS and Account settings must be configured. The easiest way to configure ZCS is from the administration console.

Exchange 2003/2007/2010 Setup Requirements.

Either a single Active Directory (AD) must be in the system or the global catalog must be available.

The ZCS server must be able to access the HTTP(S) port of IIS on at least one of the Exchange servers.

Web interface to Exchange public folders needs to be available via IIS. (http://server/public/)

ZCS users must be provisioned as a contact on the AD using the same administrative group for each mail domain. This is required only .

For ZCS to Exchange free/busy replication, the Exchange user email address must be provisioned in the account attribute zimbraForeignPrincipal for all ZCS users.
