Hello,

We have recently replaced a Windows 2008 SBS (Exchange 2007) with a new server Windows 2012 (Exchange 2013).

All users are experiencing problems when they attempt to reply to [internal] emails submitted prior to the migration.

Message is:
This e-mail message cannot be delivered to %Email% because the e-mail address is no longer valid.

This is creating major havoc.  Any assistance would be greatly appreciated.

Regards,
Real-Timer

Hello,

This issue you are experiencing is due to the way Exchange routes email internally and is explained in my article here - http://www.experts-exchange.com/Software/Server_Software/Email_Servers/Exchange/A_9650-NDRs-and-the-legacyExchangeDN.html

To resolve the issue, you will need to create new X500 addresses on your mailboxes that match the old legacyExchangeDN values.
