user account can't connect to exchange mailbox

I have a problem I need help with!  I have a user that I disabled the account in AD.  After reenabling the account, you can't send email to it.  The error message I get says it reached the system but delivery was refused.  I tried to login to the users OWA and that doesn't seem to work either.  Something is messed up and I can't find it.  Help!!

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. 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.
