We have an issue with the DST updates and a Mailbox calendar. We have updated the Exchange server and as well updated the Windows OS's which are all showing the correct time. However, thier is 1 users mailbox that other users view which is causing us a problem. All users are running Windows XP and Outlook 2003 The user in question views thier own mailbox and the times in his calendar appointments are correct, but when another user views his mailbox, the appointments are off by 1 hour. They are viewing the first users mailbox as a shared folder in Outlook. When we change the PC time on either workstation it updates the other but we cannot seem to get both PC's to show the correct time in Windows as well as the correct times in the Calendar. It is strange that they are viewing the same calendar but the times do not show as correct on all of them. Would this be because of a windows time issue or Outlook? Thanks
