PC MAPI: Err Msg: MAPI ERROR: Unknown Recipient (93176)
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 Q93176 SYMPTOMS
If you follow the directions on the MAPI technical reference disk (included
with Microsoft Mail for Windows versions 3.0, 3.0b and 3.2) to create and
use HELPREQ.EXE, you may receive the following error after you try to send
a help request to yourself:
MAPI ERROR: Unknown Recipient
CAUSE
HELPREQ.EXE does not deliver the help request correctly because the code in
the HELPREQ.C F ProcessHelpRequest section interchanges the recipient name
and the recipient address values. It doesn't work when you send Mail to an
address such as /network/postoffice/johndoe. It does work correctly when
you send Mail to a resolved name (such as John Doe), contrary to what is
listed on page 40 of the Microsoft Mail 3.0 "Technical Reference."
The Microsoft Mail "Technical Reference" also shows incorrect syntax for
the address, omitting "ms:". It should be "ms:network/postoffice/johndoe"
instead of "/network/postoffice/johndoe".
STATUS
Microsoft has confirmed this to be a problem in Microsoft Mail for Windows
versions 3.0, 3.0b, and 3.2. We are researching this problem and will post
new information here in the Microsoft Knowledge Base as it becomes
available.
RESOLUTION
You can resolve this problem by interchanging the values for
"recip.lpszName" and "recip.lpszAddress" in the following section of code
in HELPREQ.C. The value assignments shown below are correct.
Partial Section of Code for HELPREQ.C
BOOL FProcessHelpRequest(HWND hDlg, BOOL fSend, BOOL fReadDialog)
// Now we need to create a message with this file as the attachment
recip.ulReserved = NULL;
recip.ulRecipClass = MAPI_TO;
GetDlgItemText(hDlg, IDD_TO, szValue, cbValue);
-> recip.lpszName = NULL;
-> recip.lpszAddress = szValue;
