Can you give some more details about the issue you’re having? I haven’t done this before, but I think the process would be something like this:
1. Receive email w/ Excel attachment via POP3 adapter.
2. Use a receive pipeline to extract the attachments from the email. The attachments are additional message parts. You may need to write a custom pipeline component to do this.
3. Connect a file send port to the email receive port using filter expressions. Configure the file mask with a “.XLS” or “.XLSX” extension, so that the files will have the correct extension.
