Dear all,

I upgrade my exchange 2007 environment to exchange 2010, exchange 2007 is decommissioning now.
We are facing a problem now with POP 3 users using outlook express or Microsoft outlook; the users are able to receive emails from inside or outside. But when they try to send email, the attached error appears.
How I can solve this?

Thanks  Error while sending
