问题
I have a little VBA macro to save attachments in Outlook using the following snippet
For Each objAtt In objSourceItem.Attachments
strFile = strPath & objAtt.FileName
objAtt.SaveAsFile strFile
Next
This works for all types of attachments except for ChemDraw attachments. I get an error saying that "Outlook cannot perform this action on this type of attachment" I am not sure if this specific to ChemDraw, but I maybe it has to do with file extension and Outlook not recognizing the file format. Anyway, this http://www.cambridgesoft.com/services/documentation/sdk/chemdraw/cdx/General.htm has info on ChemDraw type files. Any help is appreciated. Thanks!

If this is an embedded OLE object in an RTF message, Outlook will not be able to extract the actual file data from the attachment (which is an OLE storage blob - IStorage).
