The OneDrive for Business sync is a must. Initially I had attempted to just log into it as it is part of Windows 8.1, but the students couldn't log into it. After speaking with a member of the tech department, we came to the conclusion that it needed to be downloaded. This requires quite a bit of time, but it is absolutely necessary if you desire for students to be able to access their files very quickly. In the long run, the sync will save time.
Students can create, move, and save files in Office 365 by many methods. This tutorial gives students an overview of accessing them through the file explorer (must be installed by the process in the video above), any Microsoft Office product, and the Office 365 web version.
