I have an HTC Desire and I'm experiencing some of the problems that others are experiencing in that my email has worked beautifully until last week and now my incoming emails won't sync with my msn account.  My phone provider gave me several different incoming mails port to try but nothing seems to work.  I've been getting messages such as:

"Your incoming server does not support SSL. Please modify your incoming server's security type."  (Even changing the security type doesn't work)

"Can not connect to the mail server to verify your accout information.  Your server is not responding."

I've also received a message indicating that the security certificate is not valid.

I've tried many of the things that have been posted. 

I'd like to make sure that the server information that my provider game me is correct, because it is different from the port that has been working.  I would appreciate help!

Thank you!
