Lack of a certificate doesn't cause the problem you began with. But a certificate is a Really Good Idea if access from the Internet-at-large is being allowed.
And one wouldn't have normally enabled S/Mime by accident. Could someone else have done that? If you don't think so, perhaps you could be a bit more descriptive about what is showing up on the screen - word-for-word repetition works wonders when trying to get help via e-mail. Or take a screen shot, post it to a picture-hosting website, and post the URL to that here.

It is Exchange 2003. I've been reading and it looks like I goofed pretty badly from a security perspective by not setting up a certificate. I've got them connecting on 80 instead of 443. I'm still not clear about the application of the S/MIME control B. Smith mentioned, but I don't think I need it in this case. I'm thinking that if I get the certificate working there should be no problems connecting from a public computer. does that sound right to you? _____ From: Carl Houseman [mailto:[EMAIL PROTECTED] Sent: Tuesday, June 24, 2008 12:18 PM To: MS-Exchange Admin Issues Subject: RE: Using OWA on a public computer You seem to have, shockingly, omitted the version of Exchange... Doesn't sound like 2003 behavior. Carl From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Tuesday, June 24, 2008 12:08 PM To: MS-Exchange Admin Issues Subject: Using OWA on a public computer 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 ~
