You may receive error messages when you try to download the Offline Address Book on behalf of another user in Exchange 2000 Server (842633)

SYMPTOMS

Suppose that the following conditions are true:

You create a new user in Active Directory Users and Computers. (This article refers to the new user as User A.)
You do not enable a mailbox for the new user, User A.
You grant User A the following permissions to the mailbox of another user, User B:
- Full mailbox access
- Read permissions
- Send As permissions
User B is a mailbox-enabled user.

When you log on to a Microsoft Windows-based computer as User A, you can create a profile for User B, a mailbox-enabled user. You can send and receive e-mail. However, when you try to download the Offline Address Book on behalf of User B in an Exchange 2000 Server environment, you may receive the following error messages:

An error occurred while opening the Exchange 2000 offline address book files on the Exchange 2000 server. see your administrator

Microsoft outlook could not download your offline address book. Unable to download the offline address book. The address book could not be accessed.

If you examine the Outlook synchronization log, you will see text that is similar to the following:

Start the MFCMapi.exe utility.
Click Session, and then click Logon and Display Store Table.
Choose the profile for User B and the pass credentials for User A.
