"Cannot Connect" warning...

Just recently, I noticed I wasn't getting notifications from my email account. I had it set to check every 4 hours. Last few days didn't get anything and when I go online with my laptop there is mail there. When I go into my account on my Expo and select the Send and Receive button this is the error I get.

Cannot connect with current connection settings. To change your connection settings, tap Settings.

SO I do...

I get the MEdia Net screen saying it is preconfigured and connot be modified.

So, what happened and how can I fix it??? I can't think of anything that I have done or changed. I turned off the phone and turned it back on and the same thing is happening. I can make/receive calls and send text messages and Mulitmedia messages, but not the emails.

Thanks for any help you can provide.

another question..

under the GPRS authentication, what should it be?

PAP or CHAP? and what does this mean?

check your proxy setting, it should be disabled. enable it only when you want to use ATT'S WEBSITE
The Proxy Mgr is located in the Tools Menu

Thank you, I went to check the proxy setting and that was the issue!!! I also checked the MEdia Net and that was correct. Checked the ability of the email and it WORKED!!!
Yay Hoo!!

Thank you so much,

i disabled this and i still can't connect through the ATTCM or the dial up networking.  I can see that the phone is connected to the computer.  this is really frustrating.
