PC MAPI: MAPIFindNext Not Recognizing MAPISaveMail Message IDs (107755)
The information in this article applies to:
- Microsoft Mail for Windows 3.0
- Microsoft Mail for Windows 3.0b
- Microsoft Mail for Windows 3.2
This article was previously published under Q107755 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.
