Saving e-mail from MS Outlook to OneDrive is easy: with one mouse click you save your e-mail as msg file in an OneDrive folder. Attachments can be archived separately as well (one extra mouse click). MailToFile sets the time-date stamp to the send moment and the e-mail will get a unique file name, based on sender name, send date time and subject. No duplicates anymore of the same e-mail!
