YEAR 2000 READINESS DISCLOSURE
The following year 2000 (Y2K) test considerations should be viewed as high-level testing recommendations that organizations can use to scope and implement their Y2K efforts. Each solution being assessed is unique, and deserves tailored testing to completely assess its end-to-end Y2K readiness. Consequently, any solution or product tests that do not go beyond these minimum recommendations may be insufficient to determine readiness. Please ensure you assess the entire solution.

When you are performing Y2K tests in an Exchange Server messaging environment, you may want to advance the system time clock to the appropriate time testing period.
IMPORTANT: Only advance and roll back system time in a test environment, not in a production environment. Performing such an operation in a production environment may cause the loss of all pending mail in the system, replication problems, and may require that the Microsoft Exchange services be restarted.
A few important things should be considered when you are modifying the system time for the purpose of testing:
| � | All Y2K test scenarios must be valid and realistic. Invalid test scenarios produce invalid and meaningless results. |
| � | Rolling the system time back after it has been advanced does not constitute a valid test scenario because it is not realistic. Unpredictable results are to be expected if the time is rolled back while messages are pending in the system. |
| � | Consider setting up a test environment that simulates part of your Exchange Server topology. When this is set up, change the system time on all servers to December 31, 1999. Then start sending messages, and let the date roll over to January 1, 2000. |
Example
All pending messages in the Exchange Server e-mail system will be rendered undeliverable if the system clock is advanced beyond the default messaging time outs. The diagnostic code for the non-delivery report (NDR) will indicate that the maximum time has expired on the messages. The result, in this case, is normal and to be expected because all maximum timer values on these messages have already elapsed.
To test the system behavior in a specific time period, you may advance the system time to or just before the time period you want to test. Start your testing by observing the proper transition to the specific date. After you have concluded the tests, you may then roll back system time to the current time and restart services.
Microsoft understands the critical nature of the Y2K issue for organizations. Information technology professionals who are responsible for the Y2K health of Microsoft products used in their environments need to understand how Microsoft has tested its products. The numbered list below represents the framework used by Microsoft to test the Y2K date handling capabilities of Microsoft products.
| 1. | The product stores and calculates dates consistent with a four-digit format throughout its operational range. If the product allows the user to enter a two-digit short cut for the year, the product recognizes the year consistent with a four-digit format. |
| 2. | The product correctly executes leap year calculations. The product does not use special values for dates within its operational range for data. |
| 3. | The product functions into the 21st century, through the end of year 2035. |
Microsoft continues to test for Y2K issues as new versions of products or service packs are produced.
NOTE: All references to "dates" refer to using either four digits or two digits for the YEAR portion of the date. This testing criteria does not constitute a warranty or certification expressed or implied, of any kind.
