ID: Q239009

The information in this article applies to:
  • Microsoft Exchange Server, version 5.5
IMPORTANT: This article contains information about editing the registry. Before you edit the registry, make sure you understand how to restore it if a problem occurs. For information about how to do this, view the "Restoring the Registry" Help topic in Regedit.exe or the "Restoring a Registry Key" Help topic in Regedt32.exe.

SUMMARY

Some SMTP servers use and support time zone declarations outside of those specifically defined in RFC 822. Microsoft Exchange Server 5.5 can be configured to support these new time zone specifications. This article describes how to configure this additional support.


MORE INFORMATION

To configure the Exchange Server Internet Mail Service to use a time zone not specifically defined in RFC 822:
WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

For information about how to edit the registry, view the "Changing Keys and Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe. Note that you should back up the registry before you edit it. If you are running Windows NT, you should also update your Emergency Repair Disk (ERD).

  1. Start Registry Editor (Regedt32.exe).


  2. Locate the following key in the registry:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIS
    \ParametersSystem\InternetContent
    NOTE: The above registry key is one path; it has been wrapped for readability.


  3. On the Edit menu, click Add Value, and then add the following registry value
    Value Name: NewTimeZones
    Data Type: REG_MULTI_SZ
    Value: New Time Zone;Time Offset
    where New Time Zone can be any string of three characters. The Time Offset should be in the following format: +/-XX:XX; expressed in hours (0-12) and minutes (0-59). For example:


    4. Value: LCL;-7:00
  4. Quit Registry Editor.


  5. Stop and restart the information store and the Internet Mail Service.


Note that these time zones are static definitions that do not take into account Daylight Savings Time. Manual corrections to this registry value are necessary to maintain the correct time zone offset. The Outlook calendar and task can be configured to remind you in advance.
