Cannot send mail from Outlook webmail

It's possible as IE actually installs both IE and Outlook Express although in th Beta formats it only installs IE but you don't know what links have been broken to OE and what other services no longer run.

You might be able to remove IE Beta by going to the control panel and uninstall it though from previous experience I've found that it doesn't uninstall well and I've had to perform a wipe of the HDD the format and reinstall from scratch.

If this is the only differences between the computers it would be a safe guess that the IE Beta is the problem.

Yes beta 2 has lots of problems, if you can remove or roll back do it. I use the the new stuff only if I can remove it fast. Check your settings, permissions and be sure your company supports the new product's before trying out the new stuff. Always create a restore point and and have a back up to go back to.
