Using Classic Outlook on Windows for personal email, calendar, and contact management
As of 7/1/2024, I can't drag and drop, or save/download an attachment directly from the email to my desktop.
From the dropdown menu on the attachment in the email:
I can Preview the document and I have a few options there
I can open an Office file in the browser or desktop app, and after navigating around a bit I can save it on my desktop.
I can save it to OneDrive and it goes somewhere that I need to go find.
From the main email dropdown, I can open it in the browser or desktop app the same as above.
I can also select Copy, and then I can paste that attachment into another email - I can't paste it on my desktop.
Non-Office files (PDFs, graphics) have fewer options.
