I am running XP Pro and Outlook 2003. I applied the DST patch to XP, and I also ran the TZMove tool for Outlook, and I still don't understand what purpose the Outlook patch served. Anyways, ever since March 11 @ 2:00 AM, the time stamps in my email messages have been a bit odd. When viewing all messages in my inbox folder, the timestamp applied to the message is +1 hour of when the message was actually received. Upon opening the individual message, the timestamp is correct. All messages, post March 11, post Outlook patch, displayed in my inbox folder, display +1 hour of their original time receipt. I have narrowed this down to being an issue with Outlook. I run my own mail server, running POP3 and SMTP. The date and time on the server are correct. The time and date stamps in the log files on the server are correct. Upon using my webmail application (OpenWebmail), all timestamps appear correct. I downloaded Mozilla Thunderbird (mail client) and setup my email account there. All message time and date stamps appear correct in that mail application. This proves it is an issue with Outlook. How does Outlook go about flagging messages with timestamps? I tried to manually change my computer clock ahead to April 15 to see if that changed anything. It did not, so this tells me that Outlook uses a timestamp from either the mail server or from the actual message itself, which received its timestamp elsewhere. The question becomes, why is Outlook adding 1 hour to the message when it is displayed in the inbox folder? Has anyone else run into this problem? Is there a solution? The other thing I noticed is that emails I send using Outlook are being tagged -1 hour from the actual time, but this is only displayed in the recipients email client. The timestamp in my Send folder appears correctly. TIA.
