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

Consider the following scenario:

• You create a new user (User A) in the Active Directory Users and Computers Microsoft Management Console (MMC) snap-in.
• You do not enable a mailbox for 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 Windows-based computer as User A, you can create a profile for User B. You can send and receive e-mail. However, when you try to download the Offline Address Book on behalf of User B in a Microsoft Exchange Server environment, you may receive the following error messages:If you examine the Microsoft Outlook synchronization log, you see text that resembles the following text:You can examine this log by using the MFCMapi.exe utility.

2. Click Session, and then click Logon and Display Store Table.
3. Choose the profile for User B and the pass credentials for User A.
   
   Note You may have to modify the profile to prompt for credentials if you are not logged on as User A.
