Get this error when using addresses copied from Global Address List: No transport provider was available for delivery to this recipient.

I have remote users accessing my Exchange 2000 Server via POP3 access using Outlook 2000 & 2002. Originally, I had the users accessing mail via MS Exchange Server. At that time, I right-clicked each Global Address and added it to their Personal Address Book. WHen they try to send to these recipients I get the error:  No transport provider was available for delivery to this recipient. BUt, they can send outside the domain OK.

I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.
