You either need to clear the cache as mentioned above OR add X500 email addresses to everyone's mailboxes. The X500 address is the old legacyExchangeDN value of the mailbox. They look like /o=org/OU=admin group/CN=recipients/CN=Joh<wbr />n.doe<br />
<br />
If you try and reply to an old message received from someone internally, it should NDR back with what the X500 address should be for that person.

You need to update the X500 address to include the old Exchange organisation, this is a known issue and there is a KB article on how to resolve it using ADModify here: <a href="http://support.microsoft.com/kb/909271" rel="ugc nofollow">http://support.microsoft.com/kb/909271</a>
