Suggest you open the document with a text-editor and find/search for the problem link (in your original post). This info will tell you what reference is generated by SAS. I expect SAS is generating HTML-formatted output as part of your program which is being stored as an HTML document (without any specific http:// reference) and therefore the default-location resolved is the same place as the location of the Outlook "temp" attachment.
Then come back and reply to your post with (COPY/PASTE) of your SAS log output including the ODS and PROC REPORT code/diagnostic messages that SAS generated.
