If you use Microsoft’s OneDrive Groups group-collaboration feature, you’ll need to find something else soon:
According to Engadget, Microsoft will shutter OneDrive Groups on October 16th.
Once OneDrive Groups shut down, you will no longer be able to get at files and documents shared with you, so between now and mid-October, you’ll want to
move those files to your own OneDrive.
As Engadget notes, Microsoft had already instituted limits on OneDrive Groups—you can only work with existing Groups, and you can’t create new ones or add people to your Groups—but Microsoft’s shutdown announcement marks the official death knell for the service.
