You need to put out a disclaimer notice ASAP!
Yesterday I rec'd over 40 calls supposedly from "Apple Inc" telling me my "cloud" was causing a severe security risk to my Apple products. Altho I KNEW it was a scam (because I own no Apple products), others might not. Found out today that many other friends also rec'd those same annoying repeat calls all day long & even into the night until around 8 pm yesterday. I blocked every number they used to call me, but they would then just roll over to another number for their robo-dialer to use to constantly harass me (as they did to my friends also). Perhaps you, OneDrive, needs to put out a disclaimer stating it is NOT YOU who is doing all of those robocalls, just to set users minds at ease. Thanks.
