So when I run the BPA I receive this warning "Policy Change required". And when I open it the main part of the message is "The Active Directory forest functionality level has been raised.". The recipient policy is set for "users with Exchange Mailbox" and " Users with external e-mail addresses" with a storage filter of the store they are on. How do I resolve this, do I have to run domain or forest prep for Exchange to correct this?

I think I remember seeing this in the ExBPA before. But, I thought the BPA also gave you step-by-step instructions on how to correct this. Does'nt it provide you a link that gives instructions on how to change the filter?

I think this is what you're looking for http://technet.microsoft.com/en-us/library/aa998426.aspx http://support.microsoft.com/kb/903291

My "Google Fu" must be bad today, I looked for that TechNet article and could not find it. Thanks Lasse!

Hi, when you upgrade the forest to a Microsoft Windows Server 2003 native forest functional level, the Recipient Update Service may overwrite the value of the homeMDB attribute for new Microsoft Exchange Server 2003 users. This behavior may cause the mailboxes for the new Exchange Server 2003 users to be rehomed on the first mailbox store in the first storage group. we have to modify the purportedSearch attribute before you upgrade to a Windows Server 2003 native forest functional level. To do this, follow these steps: 1. Start Active Directory Service Interfaces (ADSI) Edit. (Note: Please ensure that you have installed Windows Server 2003 Support Tools. Using ADSI Edit to Edit Active Directory Attributes http://technet.microsoft.com/en-us/library/bb124152(EXCHG.65).aspx ) 2. Double-click the Configuration container, expand CN=Services, expand CN=Microsoft Exchange, and then expand CN=<ExchangeOrganizationName>. 3. Click CN=System Policies. 4. In the right pane, right-click CN=Mailbox Enable User, and then click Properties. 5. Scroll down to select the purportedSearch attribute, and then click Edit. 6. Clear the attribute, and then use the following filter to configure the attribute: (&(objectCategory=person)(objectClass=user)(mailnickname=*)(homeMdb=*)) 7. Click OK to save the change, and then close ADSI Edit. If it is not the case,please feel free to let me know.
