GENERATE_SPREADSHEET

Greetings

I'm using this SYSTOOLS tool for the first time.
I have a program that runs to generate an XLSX spreadsheet file kind of like pgm-isodate-hmstime, dot xls.

Then, it sets up and runs the following command:
SNDSMTPEMM RCP(email)
+ SUBJECT(%trim(subject))
+ NOTE(%trim(note))
+ ATTACH((%trim(path))
and runs that.

That all runs okay, and sends the email.

But Outlook refuses to open the attachment, and refuses to download it. The explanation is "cannot open". Right. Thanks a lot, Microsoft. (NOT)

BUT the kicker is that we can download the attached IFS file using FTP and it opens just like it's supposed to, and the data is good, good, good.
:(

Anybodey got a solution here?
