SYMPTOMS
When you send a message to an Exchange mailbox, you may receive the following non-delivery report (NDR):

Your message did not reach some or all of the intended recipients

Subject:

Sent:

The following recipient(s) could not be reached:

on

The message reached the recipient's e-mail system, but delivery was refused. Attempt to resend the message. If it still fails, contact your system administrator.

In addition, the following event ID message may be logged in the Application event log:

Event Type: Error

Event Source: MSExchangeIS

Event Category: General

Event ID: 9562

Date:

Time:

User: N/A

Computer:

Description:

Failed to read attribute msExchUserAccountControl from Active Directory for /o=ORG/ou=AdminGroup/cn=Recipients/cn=user.



CAUSE
This problem can occur if the msexchUserAccountControl attribute has not been set by the Recipient Update Service. In this case, the information store treats this mailbox as disabled and all local delivery attempts fail with an &quot;Access denied&quot; error message.



RESOLUTION
To resolve this problem, update the Recipient Update Service for the domain where the user account resides:
 * 1) Start Exchange System Manager.
 * 2) Click to expand the Recipients container.
 * 3) Click Recipient Update Service.
 * 4) Right-click Recipient Update Service (Domain), and then click Update Now.

After you finish this procedure, the Recipient Update Service for that domain is run. If the issue is not resolved, manually set the attribute using the ADSI Edit tool. The msExchUserAccountControl attribute should be set to 0 for an enabled user account. However, if you run the Recipient Update Service, and the msExchUserAccountControl attribute is still not set, there may be an issue with the Recipient Update Service.
