Using OWA for Exchange 2007 on a MAC

Try with Firefox on a Mac.

Here are instructions to import your certificate to your Mac: http://www.themachelpdesk.com/modules.php?op=modload&name=News&file=index&catid=&topic=19

Have tried firefox and safari.  It is three different MAC's that can hit, but not view OWA.

Follow the instructions above to import the SSL certificate.

hit what? You never need to import any certificate if you have a current install of the OS. Root certs should be there already

P.S. you need the instructions above only to export the certificate from your PC Server in .cer format. You should be able to import it into the Mac by double clicking on it. This should open the Mac keychain app. Make sure the certificate is imported into the X405Anchors folder. If you are running OS 10.5, there will be no such folder and you will have to create one.

Our Mac's never import any certs.

Another possibility is that the users may have popups blocked in their browsers. Not sure if that would torpedo the log in, but it is worth a try.
