MikeC,

I'm still in the process of obtaining the Cert from the exchange admin team.

Yes my E90/MfE is working perfectly fine and i am assuming it pulled down the cert automatically when it first sync'd.

I downloaded the Cert from outlook web acccess although when i save a copy to my PC it doesn't ask what format i would like to save it as.

i guess i have to wait for the admin team to send it to me.
