SYMPTOMS
When you try to use Microsoft Outlook to log on to Microsoft Exchange Server 5.5, you may receive the following error message:

Unable to open your default mail folders. You do not have permission to log on.

The following information appears in Event Viewer on the Exchange Server computer:

Event ID: 1021

Source: MSExchangeIS

Description: Domain/user was unable to connect as error 0x3f2

This behavior occurs in a multiple domain network where the trust relationships are correctly established and where the Exchange Server computer is located in a different domain from the users. Other users in the domain are authenticated.

This problem occurs even if a new account and mailbox are created for you.



CAUSE
This issue may occur if you do not have the correct NTFS file system permissions on the Exchsrvr folder on the Exchange Server computer.



RESOLUTION
To resolve this issue, grant permissions to the Domain Users group on the Exchsrvr folder:
 * 1) Grant Full Control permissions to the Domain Users group on the Exchsrvr folder, and then propagate permissions to all subfolders.
 * 2) Confirm that the user who cannot log on is not a member of a group that was granted No Access permissions to the Exchsrvr folder.
 * 3) Stop and then restart the directory service.
