"The username violates our guidelines"

All I see is this with absolutely now help in how to fix it. And this doesn't even make sense?

"This is the name from your Microsoft account. It will appear next to any of your posts." Right? I assume my "Name" is supposed to be where that blank under my picture is? So it seems like it's blank? It seems like everything is filled out on my page. All I wanted to do was to like someone's comments. It shouldn't be this hard.

Microsoft like most companies reaches a certain point, and they just don't care about their customers. That's all there is to it.

This appears to be an Edge issue. I was able to update my profile and leave a comment.

I used Firefox to update my profile, got a popup asking me to log in, then was able to register and comment.

This isn't a QAnon conspiracy against Republicans or Democrats. It appears to be an MS Edge bug.

Nobody brought up "QAnon" except you. This is happening to me on Chrome, so it's not "just an Edge issue".

If you aren't aware, or simply do not believe, the ongoing censorship of conservatives on Youtube/Facebook/Twitter then you are being ignorant. It is happening, it is blatant and they aren't even trying to hide it. This is not a conspiracy, just a fact. Because you aren't dealing with it doesn't mean it isn't happening.

LOL, the reason you are being censored on facebook / youtube / twitter is because you are pushing conspiracy theories that simply aren't true. The sooner you realize that the happier you'll be and perhaps, just perhaps the country can move forward and once again be the democracy that it was built on.

As to happening on Chrome, try Firefox ... worked for me.

After reading all of these I see it is currently a common issue, don't know if it will work for you, but after I signed out and then tried again to use my name it worked, although actually, I had to sign out twice then it let me use my name.
