We got a big problem with specially the password field on our OWA. Sometimes a sign is missing you can push the button an nothing happen. You will have to push the same button again. If you count the sign in the password field, one sign maeby two sign is missing. We have heard this from a lot of users. We have tried for our selfs. I would say that 20% is wrong.
We really don't know where to look is it something with cache in IO 7.0. Is it OWA server problem or is in our cisco firewall. If we use Outlook client we got no problem.
