Collaboration Data Objects (CDO) time zone tables cannot be automatically updated from the registry values of the Windows operating system on Microsoft Exchange Server 2003.

Exchange Server 2003 uses hard-coded tables to store the time zone information. These static tables are used across the different components of Exchange Server 2003. In the past, if the definition for an existing time zone had to be changed, a change had to be made to the hard-coded time zone tables in CDO, and then a CDO hotfix had to be released. After you install the hotfix in this article, CDO time zone values will be read dynamically from Windows time zone information during a service restart. A CDO hotfix is released only if a new time zone must be added to the daylight saving time definitions.
