PC MAPI: MAPIFindNext Not Recognizing MAPISaveMail Message IDs

• Microsoft Mail for Windows, versions 3.0, 3.0b, 3.2

SUMMARY

The Messaging Application Program Interface (MAPI) MAPIFindNext function may not find a MAPISaveMail ID when the last 24 characters of that message ID contain nonzero values.

MORE INFORMATION

MAPISaveMail saves a message ID with the first 16 characters containing possible nonzero values. The remaining 24 characters always contain zero values. When MAPIFindNext is used to search through messages, it will not find a MAPISaveMail message ID if the last 24 characters of that message ID contain nonzero values. The characters beyond 16 characters contain information MAPI uses to speed up MAPIFindNext calls.

In order to access a message saved with MAPISaveMail, use MAPIReadMail. The first 16 bytes is the only information necessary for MAPIReadMail to open the message.
