I am not able to reply to messages in Outlook Mobile Access using IE 7 with Vista as the operating system. I do not have this issue when I use IE 7 with Windows XP as the operating system. When I try to reply I get the reply window and can update the 'To:' , 'Cc...', and 'Subject:' fields but I am not able to type in the text message field. The text message field has a red 'x' in a white box in the upper left hand corner.
I have successfully added the correct certificate from the Exchange server. I have compared the 'Custom level' under the 'Security' tab and the 'Settings' under the 'Advanced' tab between the two operating systems.
Does anyone know what is causing this and what I can do to correct it?
