I'm beginning to think I need a subscription from Neoblog to appear higher in my list. I have not tested this, so let me know if there are any issues, but here is the information he has posted.

If you use Outlook Web Access and have recently upgraded to Vista you will find that you can’t reply or do any action on an email, typically the edit area shows a ‘image not found’ red x in the corner.
This is because Windows Vista no longer includes support for the ActiveX control that is used for HTML editing in Outlook Web Access, you need to apply a hotfix to Exchange.
Source, more details and the link to the fix: neoblog » OWA and Vista
