  Q256986 Description of the Microsoft Windows Registry

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: If you use Registry Editor incorrectly, you may cause serious problems
that may require you to reinstall your operating system. Microsoft cannot
guarantee that you can solve problems that result from using Registry Editor
incorrectly. Use Registry Editor at your own risk.

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:

  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.
