I have a client running Outlook 98 on Windows XP SP2. Sometimes, when he tries to reply or forward an email, Outlook crashes. As far as I can tell, it only happens with some HTML messages, but no plain text messages.
I have tried creating a new PST file and importing all the emails from the old PST file but it doesn't seem to have helped.
They no longer have their Outlook 98 CD, so I can't re-install the software.
