When I send an email from Outlook/OWA, on the receiving side, the time stamp is 3 hours late. Please see the below example, I actually sent the email at 9:47am, on the receiving side the time stamp on the email is 12:47am when I replied it, the time is 9:48am.

Did you check time zone settings on your Desktop and the Sending mail server? make sure they are reflecting your time zone and correct current time.... Exchange server will sync its time from its PDC ( the Domain controller) here is some info for you incase you may need it http://www.windowsnetworking.com/articles_tutorials/Configuring-Windows-Time-Service.html Also check this one to double make sure your have not skipped any step. http://www.raymond.cc/blog/archives/2007/10/30/why-sent-email-arrives-in-mailbox-with-incorrect-date-or-time/ ocd Oz Casey, Dedeal, Microsoft MVP,Exchange Server, MCITP (EMA), MCITP (EA), MCITP (SA) MCSE 2003 M+,S+ MCDST, Security+; ,Project+; ,Server+, ,http://smtp25.blogspot.com,(Blog) http://telnet25.wordpress.com(Blog) This posting is provided AS-IS with no warranties or guarantees and confers no rights.

make sure server & workstations are sync with AD time. also apply latest patch of DST.Sajjad

Hi OZ, This is normal behaviour if you send email to users who is in other time zone, (You can see header ) of email and can see this. Also to understand this time difference you should convert time zone into one time zone , let say UTC+5:30 then match all time. if you are not getting any delay in email receiving and recepient is on other country then it OK.Anil

Checked all the suggestions, no luck. The email was not sent to different time zone, actually, the email sent by my co-working who sat next to me having wrong time stamp. One thing I did not mention was that exchange server was located in Vancouver and move to Toronto in August 2010, since then the time was wrong, but I had the IT guys checked all the setting and it was correct. Any hidden setting we need to set when moving the server to different time zone. It is a mystery!!! HELP!!!

Your admin needs to use the "copy to reserved accounts" option in the regional settings. since the server was moved after its installation, those accounts are prb still running on the West coast settings

Great! It works. Thanks lafontma and everybody. :)
