DOCUMENT:Q265391 23-OCT-2000 [exchange] TITLE :XADM: Exchange Server Honors Message Expiry Even If Incorrect PRODUCT :Microsoft Exchange PROD/VER:winnt:5.5 OPER/SYS: KEYWORDS:exc55 ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Exchange Server, version 5.5 ------------------------------------------------------------------------------- SUMMARY ======= Messages that come into an Exchange Server site may be rejected without notification to the sender if the message has an expiry time and it is earlier than the Exchange Server computer's current date and time. MORE INFORMATION ================ Users of Internet mail can set a message expiry time. This defines how long the message will stay in the recipient's Inbox. If the expiry time of the incoming message is earlier than the Exchange Server computer's current date and time, the message is discarded without notification because the Exchange Server computer recognizes the message as already expired. This behavior is by design. E-mail clients set message expiry. Simple Mail Transfer Protocol (SMTP) e-mail users should not stamp an outbound message with expiry, and when they do SMTP e-mail clients act unexpectedly if the message expiry has the current date and time as the message.
