unable to reply to or compose e-mail message

[JJ1998]

Get a box with red x when I try to reply to or compose an e-mail msg in
webmail (accessed via IE7 and Vista). I've seen solutions posted which
recommend going to options in the left task pane and selecting e-mail
security to install or upgrade the s/mime control. However this "e-mail
security" does not appear when I open options.

You are using OWA and not Microsoft Office Outlook. OWA is part of Exchange,
not Outlook, and is supported in exchange.clients

Anyway; tell you Exchange admins to apply the OWA updates released about a
year ago.
