Iphone4 cannot get mail while on the local wifi

I've connected a few iphones to the MS SBS 2003 mail system and the problem is with all of them. When I leave the office (get off the wifi) the mail sync's very well both on my home wifi or 3G. As soon as I'm within the wifi of the office I continue to get a message on the iphone that states "Cannot get Mail, the connection to the server failed".
I do get mail sometimes but not always and it hardly ever seems to send when I'm within the wifi.
I have three mail accounts on the phone, they all seem to receive mail randomly while in the wifi zone.

Thanks,

I've followed the instructions and have added "stopping and restart the DNS service plus turned off wifi and turned it back on again on the phone", yet it still gives me the error. Does it need some time to refresh?

What is the FQDN of your server or are you using an IP Address?  Is your FQDN something like mail.domain.com and have you created the correct DNS zone / A Records?

I used owa.domainname.ca instead of my actual mail.domainname.ca. just following blindly without thinking I guess.

Thanks for your help, greatly appreciated.
