How do I add an Exchange accout with a custom SSL port ?

[spiny_uk]

Hi,
I'm trying to add a new work email account to my HTC 7 Pro (running 7.5) and I can't seem to get it to work as the provider uses a non standard SSL port - 444 instead of 443.
How do I set this up ?
The account works on Outlook on my Pc and Mac (and an iPhone) as I have the option to specify a port number, but I can't see where to do this on the phone.

using the mail.server.com:444 as the server doesn't seem to work either.

is this even possible on windows phone ?

thanks, Phil.
