Utility to sync outlook contacts with T4x phone

[tsukraw]

Hey guys,
Hoping someone has found such a utility.
What i have is a customer who uses outlook.
What we would like is some kind of utility or way to have there outlook contacts synced with the phone, that way when a call comes in and if it matches caller ID from the phone book it will display caller ID in the format the user has the contact in there outlook.
has anyone ever ran across such a thing?
Even if we had a utility that would automatically every so often export there contacts to a file that we coudl then format into a xml document on the web server th phone could see.

just looking for idea on how we could accomplish this.

Thanks
