Internet Explorer 7 Crashes when Posting Messages in OWA 2003

Posted on January 8, 2009 by Daniel Petri in Exchange Server with

We all love Outlook Web Access (OWA) in Exchange Server 2003. However when using Internet Explorer 7 (if you still don’t have it read Download IE7) to browse to OWA 2003 we’ve encountered a nasty problem:

You compose a new message:

You click on Send, and boom:

Microsoft has acknowledges this to be a problem (read MS KB 924334 for more info) and has posted a hotfix that needs to be installed on the Exchange servers.

Download the hotfix right here: Update for Exchange Server 2003 SP2 (KB 924334) (2.8mb)

Note: During the installation of this hotfix the Exchange Information Store service will be stopped and re-started, therefore plan for a couple of minutes of downtime for your mailboxes.

Important note about using Front-End and Back-End servers: If you have a FE/BE setup you MUST install this hotfix on all Front-End servers BEFORE installing it on the Back-End servers. Otherwise you might have issues with OWA (thank you Guy Teverovsky for this input).

After installing the hotfix on the server you must uninstall the S/MIME control from any computer that’s using IE7, and reinstall the new S/MIME control from the server.

In order to remove the S/MIME control use Add/Remove Programs from the Control Panel.

After removing the old S/MIME control, use OWA’s Options screen to install it again (this time it’ll be the new version):

When you’ll look at the Add/Remove Programs applet (and on the Exchange server in the Exchweb folder) you’ll see you’ve got a new version:

Note: Microsoft has released a new version of this hotfix – see updated download link below. After installing the new version you will see a new version number in the Add/Remove Programs applet:

Users should now remove the older hotfix and re-install the new one.
