Product Maintenance: While Microsoft continues to recommend that customers install the most current Service Pack/Release for non-Year 2000 reasons, we understand that, for many reasons, this may not be possible. In order to aid our customersÆ Year 2000 efforts, Microsoft intends to maintain Exchange Server-Enterprise 5.5 Service Pack 2 as compliant through January 1, 2001. Newer Service Packs are also to be maintained as compliant, and may include additional non-Year 2000 updates. This is intended to minimize the Year 2000 as a reason to upgrade.
Note 1: For the entire product to Compliant Exchange 5.5 Service Pack 2 is required. However, if the following components are not installed, Microsoft Exchange Connector for Lotus cc:Mail, Microsoft Migration Wizard for cc:Mail, Microsoft Mail DirSync, then Exchange 5.5 Service Pack 1 is Compliant.
Note 2: Please see the details on http://www.microsoft.com/technet/year2k/product/product.htm for the latest information on Windows NT Server. Exchange is Compliant when used with the Compliant or Compliant# version of Windows NT Server. This includes Windows NT Server Service Pack 3 with the latest hot fixes.
This document covers the products that are included in the Microsoft Exchange Server Enterprise edition, or that can be purchased separately. In addition, it covers the individual components that can be added to the Exchange Server Standard edition. The components combined together are referred to as Exchange. There are individual components that may be called out specifically, in order to give more details on how they use dates or how some features should be tested. Year 2000 information for the Exchange clients and Outlook are covered in their corresponding documents.
What are the prerequisites?
* Exchange 5.5 Service Pack 2 is required if any of the following components are used on the Exchange server.
- Microsoft Exchange Connector for Lotus cc:Mail
- Microsoft Exchange Migration Wizard for cc:Mail
- Microsoft Mail DirSync
Below are Knowledge Base articles that describe the problems in each component, not the fixes themselves. The fixes for the problems are contained in Service Pack 2. If any one of the above is installed on the userÆs computer, then Service Pack 2 needs to be applied.

If none of these components are used, then Exchange 5.5 Service Pack 1 is sufficient.

Microsoft Exchange Server Database:
Extensible Storage Engine (ESE) and the Exchange Server Database Engine use an internal date range in years from 1900 to 2156. ESE uses the JET_LOGTIME structure.
Date/Time structures for ESE:
JET_LOGTIME structure (8 char's (bytes) representing date-time)
Year is encoded as: char bYear; Date range for this structure is: 1900 û 2156.
Microsoft Exchange Information Store :
Internally the Exchange Information Store stores year dates in 4 digits using the types FILETIME or SYSTIME. There are a few cases in which the information store accepts a 2-digit year in those cases where other components hand the information store an Internet standard RFC 822 message. In this case the information store stores these dates as the number of seconds since Jan. 1, 1986. This gives the information store a range of 1986 û 2085.
In the cases where dates are passed to the information store as a UTC_TIME string, it will convert the 2 digits using 1951 as the cut off for the range. If the year is in the range 51-99 the date is converted to be 1951-1999. If the year is in the range 00-50, the date is converted to 2000-2050.
Date/Time structures the Exchange information store uses:
