OneDrive is Microsoft's cloud storage service.
Files created from the Microsoft 365 website are automatically saved to your OneDrive.
The easiest way to save to OneDrive is to sign into one of your Office apps.
Once you are signed in, your OneDrive will become available as a location to save to:
When you browse your OneDrive files, icons appear to give you more information about the file.
If you are working on an installed app, Install the Box Drive. When you save your file, browse to the Box folder on your computer.
If you are using an app from the Microsoft 365 website, choose from Save As > Download a copy and browse to your Box folder. Note that this will not keep your files in sync.
No. You will need to move your files off of OneDrive. Before you leave UB, you should move your files to a free OneDrive account. See Transition from UBIT Services.
