A family of Microsoft word processing software products for creating web, email, and print documents.
Update: Windows Outlook will open a preview if I single click on the file in the email, but gives the subscription requirement if I try to double click on the file.
The file is attached normally, not using OneDrive.
(I'd welcome suggestions for removing the OneDrive option because I often drag a file over and Outlook attaches it to OneDrive because I dropped it on the left half of the email window. I do not want the OneDrive option because I find the OneDrive user interface unintuitive/non-user-friendly compared to DropBox).
