XADM: Migrated Mailbox Cannot Receive Mail (812279)

RESOLUTION

To resolve this problem, use ADSI Edit to remove the value from the msExchUnmergedAttsPt attribute. To do so, follow these steps. Warning If you use the ADSI Edit snap-in, the LDP utility, or any other LDAP version 3 client, and you incorrectly modify the attributes of Active Directory objects, you can cause serious problems. These problems may require you to reinstall Microsoft Windows 2000 Server, Microsoft Exchange 2000 Server, or both. Microsoft cannot guarantee that problems that occur if you incorrectly modify Active Directory object attributes can be solved. Modify these attributes at your own risk.

1. Start ADSI Edit from Windows 2000 Support Tools.
2. Expand Domain NC [Your_Server.Your_Domain.Domain] \DC=Your_Domain, DC=Domain\CN=Users.
3. Right-click the mailbox that you want to edit, and then click Properties.
4. Click the Attributes tab, and then in the Select which options to view list, click Optional.
5. In the Select a property to view box, click msExchUnmergedAttsPt.
6. Click the Value box, and then click Clear.
7. Select the value in the Edit Attribute box and then press DELETE.
8. Click Apply, and then click OK.
