Why does default option sharing OneDrive for Business docs now give link anyone can use to edit?
This is new and is worrying lots of users trying to quickly share docs which the presume will remain confidential within OneDrive for Business
I noticed this as well as it's not the default way we'd like OneDrive files to be shared. You can update this in the OneDrive Admin Center. Under sharing set the default sharing links to 'direct - only people who already have permission'. Then, by default, only those in the 'to' line will have permissions.
To be precise, direct links (aka restricted links) give access only to people who already have permissions, as stated in the option.
This is clearly evident if you choose Get link instead of Share.
