So I've just discovered that while we have emails from external sources, outside of a small whitelist, going to our students blocked evidently shared files will potentially breeze right past that. One, the share email will go right through because the initial share email itself is coming from Google not the external email address. Two, it looks like the "easy" way (Sharing Options under Drive and Docs) of blocking that also force turns off sharing documents to the outside, which is probably desirable anyway.
My question is would this potentially impact things like filtering programs (Bark, GoGuardian, ect) or other oauth logins that request access to the drive (that should be managed by App Access Control anyway)? I'm mostly looking at any fringe cases that could impact legitimate student usage like submitting documents for a K12 contest, though I'd think that would be via the teacher not themselves. I'm also curious whether ya'll are blocking it for all your students or only those under a certain grade since I can see juniors and seniors needing to be able to have external file access for college applications and whatnot.
I'm also assuming this doesn't prevent students from viewing publicly viewable external documents and only, presumably, prevents the student from being specifically added to that documents privilege's.
