Hi ,

I am trying to Send mail through mapi wih any no of attachments.

lReturn = MAPISendMail(0, 0, mapi_Message, mapi_Recipient, mapi_File, MAPI_DIALOG, 0)

MAPISendMail return SUCCESS if no of attachments less or equal to 4

otherwise it is returning failure

XML

<pre lang="vb">With mapi_Message

         .Subject = &quot;Packed File&quot;
         .NoteText = sMailMsg
         .Flags = 0
         .FileCount = kCount + 1
         .RecipCount = 0
         .Reserved = 0
         .DateReceived = &quot;&quot;
         .MessageType = &quot;&quot;
     End With</pre>


For iCount = 0 To UBound(Attch)
<pre lang="vb">With mapi_File(jCount)
    .Filename = sTempFileName
    .PathName = sTempFileName
    .Position = iCount 
    .FileType = &quot;&quot;
    .Reserved = 0
End With</pre>

Maybe it's not a number of attachments, but size limit?
Did you check with one large attachments and with many small ones?

Yes it is allowing to attach single file whose size is 20mb

Without knowning what the error message was, anything anyone tells you is just guessing.

But, the most common problem is that your total size of attachments exceeds the limit specified by your SMTP server, usually 10MB. Oh, and that size limit is the Base64 encoded size of your attachments, NOT the "size on disk" of them.

10 mb size limit is correct but if iam attaching 4 files of total size less than 10 mb it was successfully attached

Then you need to get with the owner of the mail server you're using and see if the limit can be increased for the user that your coding is using to send mail.

And it is returning MAPI_E_FAILURE
