SYMPTOMS
On a server that is running Microsoft Exchange Server 2007, Exchange Server 2007 may drop recipients out of the offline address book. This problem occurs when the primary SMTP address of a recipient is changed by using the Exchange Management Console after the SMTP address is first created.



CAUSE
This problem occurs because the recipient's primary SMTP address was changed without updating the Mail attribute. If the Mail attribute does not match the primary SMTP address, the recipient will be dropped when the offline address book is generated.

Note You can use either the Exchange Management Shell or the Active Directory Service Interfaces (ADSI) Edit tool to modify the SMTP address and the Mail attribute. Perform this change outside the Exchange Management Console.



WORKAROUND
To work around this problem, use one of the following methods:  Use the   argument in addition to the   argument when you change the e-mail addresses by using the Exchange Management Shell.

An example of a command that uses these arguments is as follows:

Set-Mailbox  -EmailAddressPolicyEnabled:$False -PrimarySmtpAddress   -WindowsEmailAddress  

 Use the ADSI Edit tool to manually correct the Mail attribute on the user object in the Active Directory directory service.

To locate users who are experiencing this problem, you can use the following PowerShell command:

get-mailbox -resultsize unlimited | Where-Object {$_.PrimarySMTPAddress -ne $_.WindowsEmailAddress}

To make a bulk modification of users who are affected when their Windows e-mail address is set to their primary SMTP address, you can use the following PowerShell command:

get-mailbox -resultsize unlimited | Where-Object {$_.PrimarySMTPAddress -ne $_.WindowsEmailAddress} | foreach { set-mailbox $_.identity -windowsemailaddress $_.primarySMTPAddress }



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the &quot;Applies to&quot; section.
