Vista: Can't reply to messages in Outlook Web Access? Install this patch: http://support.microsoft.com/kb/911829
Vista & self signed certificates issue:-
To install a certificate when visiting a self-signed OWA server on Vista, you need to perform the following steps:
1> Run IE as an administrator (Right-click the desktop icon)
2> Visit the site.
3> Click through the certificate error
4> Click the "Certificate Error" button in the address bar.
5> Click View Certificate
6> Click Install Certificate
7> Unlike on XP, you must click the “Place all certificates in the following store” radio button, and choose the “Trusted Root Certification Authorities” store. If you don’t do this, the certificate goes in your personal store, and it isn’t trusted by IE.
