Applies to: Exchange Server 2007 SP3, Exchange Server 2007 SP2, Exchange Server 2007 SP1, Exchange Server 2007

Topic Last Modified: 2007-12-20

This topic explains how to use ADSI Edit (AdsiEdit.msc) to manually create the message transfer agent (MTA) object in the Active Directory directory service. If you want to create a mailbox on the second or successive clustered mailbox server of a Microsoft Exchange Server 2007 single copy cluster (SCC), you must manually create the MTA object in Active Directory.

To perform this procedure, the account you use must be a member of the local Administrators group. For more information about permissions, delegating roles, and the rights that are required to administer Exchange Server 2007, see Permission Considerations.

importantImportant:
If you use ADSI Edit or any other Lightweight Directory Access Protocol (LDAP) version 3 client, and you incorrectly modify the attributes of Active Directory objects, serious problems may occur. These problems may require you to reinstall Windows Server 2003, Exchange 2007, or both Windows Server 2003 and Exchange 2007. 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. Install the Microsoft Windows Support Tools. For detailed instructions, see Install Windows Support Tools.

  2. On a computer in the same domain as the second or successive clustered mailbox server, click Start, click Run, type C:\Program Files\Support Tools\Adsiedit.msc, and then click OK.

  3. If the Configuration [<domain controller name.domain name.com>] node exists, continue to Step 4. If the Configuration [<domain controller name.domain name.com>] node does not exist, in ADSI Edit, click Action, and then select Connect to.

  4. In Connection Settings, under Select a well known Naming Context, select Configuration from the drop-down list. Under Computer, click to select a domain server or to select the default. Click OK.

  5. In ADSI Edit, expand Configuration [<domain controller name.domain name.com>], expand CN=Configuration,DC=<domain controller name>,DC=<domain name>,DC=com, expand CN=Services, expand CN=Microsoft Exchange, expand CN=<organization name>, expand CN=Administrative Groups, expand CN=Exchange Administrative Group(FYDIBOHF23SPDLT), and then expand CN=Servers.

  6. Right-click the name of the second or successive clustered mailbox server on which you want to enable mailbox creation, point to New, and then click Object.

  7. In Create Object, click mTA, and then click Next.

  8. On the Attribute: cn page, in the Value box, type Microsoft MTA, and then click Next.

  9. On the Attribute: transTimeoutMins page, in the Value box, type 20 to set the transTimeoutMins attribute value to 20 minutes, and then click Next.

  10. On the Attribute: transRetryMins page, in the Value box, type 5 to set the transRetryMins attribute value to 5 minutes, and then click Next.

  11. On the Attribute: mTALocalDesig page, in the Value box, to set the mTALocalDesig attribute value, type the host name of the second or successive clustered mailbox server on which you want to enable mailbox creation, and then click Next.

  12. Click Finish to create the MTA object.

  13. In ADSI Edit, right-click the new MTA object, and then click Properties.

  14. In the CN=Microsoft MTA Properties dialog box, select the Attribute Editor tab, select the legacyExchangeDN attribute, and then click Edit.

    noteNote:
    If you are on Windows Server 2003, click the Show optional attributes check box to view the legacyExchangeDN attribute.
  15. In String Attribute Editor, in the Value box, type the legacy distinguished name (DN) in the following format:

    /o=<organization name>/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)/cn=Configuration/cn=Servers/cn=<CMS name>/cn=Microsoft MTA

    For example, type the following in the Value box:

    /o=First Organization/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)/cn=Configuration/cn=Servers/cn=Server01/cn=Microsoft MTA

  16. Click OK two times, and then exit ADSI Edit.
