Connect to OpenFire using Windows Messanger 5.1

Hello Guys

Windows Messanger 5.1 is normally used with MS Exchange.

I tried the following, Install Windows Messanger 5.1 > Select Exchange Messaging Service > Entered E-Mail Address > admin@openfire.company.com > Entered > Username > Password > Domain

It does not work

Does any one know how to make it work ?

Thanks
