Nokia :: E72 After Updating Mail Is Not Sending

I finally updated my E72-1 to 031.023. On the earlier version, I could not use my Mail for Exchange with my work e-mail (i.e. work server etc). it just didn't do anything after setup. In previous posts, people said after the update, it should work fine well, it doesn't. Its the same problem: After setup (with my IT guy) the MfE just doesn't load any messages. It just keeps on saying "No Messages". I have tried everything. So I have three questions:


1) When setting up the MfE, is there anything else I need to do i.e. register my work e-mail somewhere (which I did I think) or something?
2) The acces point Background: when set to "internet" it just doesn't work. It always says "Packet data not available" or "Connection not Available". The 'Internet' acces point "points" to the correct packet data set. When using the packet data set "manually", internet connects and works. Why is this so? Why can't I use my "internet" access point for connecting to the internet?
3)My third question is: For MfE, the access point is set to Internet. Could this be a problem? The only options I have is Internet, WAP services and Intranet. None of them "work".
