XCLN: Schedule+ Error: "The Schedule File Could Not Be Opened"

• Microsoft Exchange Schedule+, version 7.0

SYMPTOMS

When you attempt to open another person's appointment book in Schedule+, you encounter one of the following errors, depending on the version of Windows you are running:

• Windows NT Workstation:

        The schedule file could not be opened. An unknown error occurred.
  

• Windows 3.1, Windows for Workgroups 3.11, or Windows 95:

        The logon credentials supplied were incorrect. Make sure your
        username and domain are correct, then type your password again.
  

CAUSE

Attempting to open a schedule on a server that is in another site in an untrusted domain causes this error. This problem occurs with both site connectors and X.400 connectors.

RESOLUTION

Set up a two-way trust between the domains in which each of the computers running Microsoft Exchange Server is located.

MORE INFORMATION

Schedule+ reads the remote user's home server from the local directory service and then uses remote procedure calls (RPCs) to connect to the remote Information Store. Because the mailbox is in an untrusted domain, the error described above occurs.
