XFOR: Calendar Connector Fails With MAPI Error 80004005

• Microsoft Exchange Server, version 5.5

SYMPTOMS

The Microsoft Exchange Calendar Connector may fail to start on an Exchange Server computer that has a local replica of the Free/Busy public folder.

CAUSE

These symptoms appear when the public information store is deleted or moved to another Exchange Server computer.

RESOLUTION

Although MAPI mail clients can be re-directed to a public information store (Pub.edb), the Exchange Calendar Connector explicitly requires access to the local Exchange Server computer's public information store to complete its initialization routines.

The Exchange Server administrator will need to change a configuration setting on the server to force the calendar connector to stay focused on the local public information store. This can be done by following these steps:

1. Start the Microsoft Exchange Server Administrator program.



2. Go to the current server object and expand the properties to reveal the Private Information Store and Public Information Store objects.
   
   NOTE: If you don't see the Public Information Store object, it has not yet been added to the Exchange Server. Please ensure that this is done before continuing.



3. Double-click the Private Information Store to open its properties.



4. Click the General tab, and look for the public folder server setting near the bottom of the dialog box.



5. Change the server name to now point to itself rather than to a remote server. This will cause all MAPI clients to access the local replica for F/B information rather than using another server. This will also allow the Calendar Connector to successfully sign on to the public information store locally.

STATUS

Microsoft has confirmed this to be a problem in Exchange Server 5.5.
