Hi there, i've now used ipsCA after your post. and it works great so thanks for that. however they have asked me to put there logo etc on our page. Can you tell me how to put it on? have you edited the OWA page?
"We use ipsCA its trusted, so mobile devices work and you don't get that certificate error / warning. You shouldn't need an EV Certificate either.
and I bet I can beat all your prices (here's the best bit)....
ipsCA is free for schools!"
