DSX-80/160 and Exchange 2013

Hello Forum Members,

email for the users is fine.

We have a customer that is using a DSX-80/160 to send voice mail to users via Exchange.

This worked (works) fine for the Exchange 2007 server - using a username and password on the domain. "voicemail@ourdomain.com"

We are current running in co-exist mode - but the DSX-80/160 cannot pass the send mail test to the new

server -- the port used is 25.  We can telnet to the new server (Windows 2k12 with Exch 2013).

We can an error message from the DSX - saying it cannot verify user/password.

Any ideas here?

Thanks

Eric H.
