Because we decided to wait to move everyone to the new exchange server after this semester, I found and fixed the issue regarding IE7 crashing when sending messages through webmail.
The problem stemmed from the S/MIME installation file. That installation file fixes the red “X,” but can cause the next problem. That problem is that IE7 will crash when users click the send button on messages. This involved the installation of a hotfix on Exchange (Then, a reboot) and requires users to uninstall the old S/MIME file on their computer. Then, they have to go back to the OWA options page and install the S/MIME file again. When finished, the S/MIME version should be: 6.5.7651.60.
Here are the links that describe this:
