As of now, I am able to perform below two steps:-
1. I am able to save the Office 365 email (whole email itself) to SharePoint (online) document library as a .eml file using Logic Apps and open up in office outlook. - I am using Create File action
2. Also, I am able to save the metadata (To, From, Subject, CC) of incoming email in a SharePoint List. - I am using Create Item action
Now, I want to save the O365 incoming email attachments to SharePoint (online) list along with other email metadata. So, when email metadata is getting added in list (as per point-2 above), I want to save incoming email attachments as list item attachment. NOTE - I don't want to save incoming email attachments as individual items in a Library.
