How to get attachments from saved msg file

Hello tsibilski ,

I would like to propose a solution but using another Microsoft tool as well.

Depending on the license that you have you can create a flow using MS Power Automate that will save the xlsx attachment from an email to a folder on Sharepoint.

Then using Power Query you can retrieve the latest excel file from the Sharepoint folder. A quick way to do that is:

1. Load all xlsx files

2. Sort them by creation or modified date

3. Keep Top Rows = 1
