I figured this out earlier and thought that I would share it with the group... You have to set the Pop-up blocker settings to 'Low: Allow pop-ups by secure connections' in Internet Explorer. Once again this is only for XP SP2 users.

I am on hold with Microsoft right now, but you may already know the answer... I have Exchange 5.5 running with OWA installed ONLY users running XP with SP2 installed are having the following OWA issue: - When in OWA, if the XP SP2 user opens an e-mail and clicks either the Reply, Reply to All or Forward button, the screen disappears. - All other functions work correctly. (Users can send new e-mails, create/view calendar, etc.) They just can not open an existing mail and Reply or Forward the message. I have tried turning off the firewall on XP SP2 - No Luck The affected users can Reply and Forward all messages through OWA if on another Operating System XP users that do not have SP2 installed can Reply and Forward messages. There are no event logs or error messages What in XP SP2 is preventing the Reply and Forward message screens from appearing? Regards, Chris
