We have Exchange 2003 running on a Windows 2000 server. Most of our users use Outlook Web Access (OWA) to send and receive e-mail. On many computers (but not all) a questionmark (?) appears at the beginning of every message a person sends through OWA. How can I eliminate these question marks from appearing?
I have read that S/MIME may have to do with this but if users go to "Options" when in OWA, they only see a download button and when they click on it, nothing happens.
This problem has occured on a Windows 2000 machine with Outlook 2000. It has also occured on a Windows XP Pro / Outlook 2003 machine with all the updates. The problem did not occur on a newer Dell Laptop Windows XP Pro SP 2 / Office 2003.
Can we solve this problem centrally for everyone?
