The PR_ATTACH_MIME_TAG property contains formatting information about a Multipurpose Internet Mail Extensions (MIME) attachment.
| Header file: | MAPITAGS.H |
| May be exposed by: | Attachment subobjects |
| Identifier: | 0x370E |
| Property type: | PT_TSTRING |
| Property tag: | 0x370E001E (0x370E001F for Unicode) |
If the PR_ATTACH_TAG property contains the value OID_MIMETAG, the transport provider should look at the PR_ATTACH_MIME_TAG property to determine how the attachment is formatted.
PR_ATTACH_MIME_TAG is copied from the Content-type parameter of the inbound MIME header. The composition of the string is defined in the RFC 1521 document. The format is type/subtype, such as application/binary or text/plain.
