Microsoft Sites Blocked by Defender

For now, I don't know enough of all Defender features (yet 🙂 ) to let you know if what you've experienced so far might be normal or not. So for now I would even consider it as just as an implementation that you're only being tentatively and partially only blocked just because for the moment your company may have simply decided to temporarily start monitoring people access to some external sites they are for now considering as particularly 'sensitive'.

P.S. Anyway at same time I'd also suggest you to better check your own company policies, just to avoid you to possibly even meet unexpected side effects of your actions in particular if somehow any of these might even partially be contrasting with those same policies. 0:-)

HTHed too, and if it really did, then please feel also very free to mark this post as a solution... Thx in advance
