Out of Office Assitant in exchange 2010 is not working

Out of Office Assitant looks like its working. I can enable it from the client side and OWA, but if I send an email to anyone who has it on and has it set to do an automatic reply nothing happens, I get nothing back. I did it for my self logged in with a test user and a normal user and get no automatic replies letting them know I'm out of Office, any ideas?

Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

"I checked my EWS virtual directory and anonymous, forms, and integrated were enabled.  

What I had to do to make it work was only enable anonymous and integrated.  This makes no authentication sense, but that is what I had to do.  

If I disable anonymous and forms, it doesn't work and if I disable integrated and forms it doesn't work.  

You need both anonymous and integrated authentication on the EWS directory"

no I'm not having that same issue, my authentication is already set that way. the problem I am having is if I set my Out of Office Assitant right now, I wont get any problems, the problem is if a user send me an email they do not get an automatic reply stating that I am out of office.
