XFOR: Exchange 2000 Service Pack 1 Calendar Connector

This article describes the Exchange 2000 Calendar Connector that is included in Exchange 2000 Server Service Pack 1 (SP1).

The Calendar Connector that is included in Exchange 2000 SP1 enables free and busy lookups between Exchange 2000 and computers that are running Lotus Notes and Novell GroupWise. If you have not installed the Calendar Connector, Exchange 2000 users can send meeting requests, but they cannot see free and busy information for these users.

The Calendar Connector is included with Exchange 2000 SP1 because many customers have Exchange 2000 mail systems that coexist with GroupWise or Notes. Exchange 2000 users may need to schedule a meeting request with users on these partner computers. The Calendar Connector depends on successful folder synchronization with the partner computer. GroupWise and Notes users must be represented in Active Directory as Contacts.

Although the Calendar Connector is included with Exchange Server SP1, it is not installed automatically with the service pack. The Calendar Connector Setup program is located in the Calcon\I386 folder on the Exchange 2000 SP1 CD-ROM. After installation, the Calendar Connector executable file (Calcon.exe) is located in the Program Files\Exchsrvr\Bin folder on the Exchange 2000 server.

How to Store Free and Busy Information

The Calendar Connector always stores free and busy information in its administrative group's public folder, specifically the Schedule+ Free Busy public folder. If there are multiple administrative groups on an Exchange 2000 server, each administrative group has its own public folder. In this case, free and busy information for Exchange 2000 users may be stored in a different public folder than the free and busy information for users on partner computers.

The Calendar Connector does not support the following procedures:

• You cannot initiate real-time queries to downstream Exchange 2000 routing groups. Exchange users in routing groups that are not directly connected by the Calendar Connector to a partner system (routing groups downstream of the routing group in which the Calendar Connector is installed) are not able to initiate real-time queries. Instead, they receive the calendar data that has been replicated from the Calendar Connector’s site (routing group). If you want to provide real-time free and busy access to all Exchange users, install and configure a Calendar Connector in each Exchange site (routing group). There is no way to relay a real-time free and busy query over a Site Connector or Routing Group connector.
• You cannot use the Calendar Connector as a free and busy switch between Notes and GroupWise. Exchange does not support free and busy switches or queries from one partner computer to another by using Exchange as a backbone. In addition, you cannot use a partner computer as a backbone between two Exchange computers.
• You cannot configure multiple Calendar Connectors in a single administrative group that connects to the same partner post office.
