Go in to the mail shortcut on your homepage, click add new account and click Microsoft Exchange ActiveSync.
Click manual setup and now fill in the relevent fields.
Email address: this is your work email address in full as in firstname.lastname@example.org
Server address: Your webmail url, without the https:// bit. So remote.mycompany.co.uk/webmail
Domain: Leave this blank, it should not be necessary.
Username: This is the username as you type it when logging on to your webmail.
Password: Again as you type it on your webmail.
I can see by the url you posted that it has an ssl certificate, so leave that box ticked.
Click Next and it should then move on to the next screen asking which services you would like to sync.
After that you are done. All you now need to do is set up the frequesncy with which it sync's.
If that does not work, then you will need to go back to your IT department. The reason for it not working could be because:
a. the mobile services within Exchange Features on your Active Directory Username are not all enabled (or are not enabled at all).
b. your company uses Exchange 2010. Exchange 2010 is 64 bit and as we have just found out 64bit Exchange accounts are not yet compatible with this phone.
c. The url for your webmail is incorrect (there is a chance that the slash webmail on the end will not work, as that generally means you are required to login to a company website before logging in to webmail).
These items can only be resolved by your IT department, well actually they can't resolve b. If it is the url, then they would need to amend the a record so that it points directly to the OWA server.
