When my users connect to the Exchange server for the first time on a given computer an editor control must be installed or they won't be able to reply or create new messages. I found that I had to add the Exchange server to the trusted sites list in IE to prevent problems installing the control. I'm not sure if that is the "best" or "preferred" method but it has been working.
The problems start when they want to use a public computer, at a conference for example... I just had a person call me saying that a public computer is asking for a smart card when she tries to connect to the Exchange server. There must be a way to do this that is easier for the end users. A pointer in the right direction would be helpful. Roger ~ Ninja Email Security with Cloudmark Spam Engine Gets Image Spam ~ ~ http://www.sunbeltsoftware.com/Ninja ~
