After you migrated from Exchange 2003 to Exchange 2007, you receive an error when you try to edit your recipient policy “Default Policy”.
“Unable to edit the specified E-mail address policy. E-mail address policies created with legacy versions of Exchange must be upgraded using the ‘Set-EmailAddressPolicy’ task, with the Exchange 2007 Recipient Filter specified.”
Oké, let’s update the recipient policy! With the following command you can see the properties of this recipient policy.
Get-EmailAddressPolicy | fl Name,*RecipientFilter*,ExchangeVersion
Set-EmailAddressPolicy “Default Policy” -IncludedRecipients AllRecipients
After running this commands, you’re able to edit the “Default Policy” again.



It’s strange to find out how many sites there are about this subject I don’t know if I’ll ever need to be back, but it is nice to know I found the one that provides a lot of valuable information if this should come up for me another time
