I've had this same issue for the last two years, every single MS support person has failed and it continues to get worse.
I even resorted to moving files to One Drive because I couldn't access them anymore!!! Oh and re downloading another image or file doesn't work because after it finishes downloading, it can no longer access the file location, even though you can SEE the file icon, right there in front of you!!! Support says " Well since it's gonna take a while to download, you know how to restart a computer, right? Can We consider this issue to be SOLVED so I can CLOSE the ticket?", I said sure, only because once it finishes and restarts, support wants to be long gone.
Don't get me wrong, there ARE some very good techs out there, and because this issue didnt happen over night. It was a very gradual process...
I only noticed it when it took away all my **** files and wasn't allowing them to play with Nero . I have been complaining and ranting that something was wrong, but the deaf ears of those in support is making me believe hat reposting several times is the only way to get them to notice you, and then shove you aside for being a double poster. I think if they are so offended by it, they should be able to do something other than pushing you out , leaving your problem unanswered or unsolved.
