Trying to sign on to my Microsoft account on minecraft for switch.

Try deleting minecraft on the switch and make sure your signing in using a microsoft account.

Please let's try to wait until the current outage is fixed Chelsea

Probably your problem is related to it

Keep me posted if you need it

Usually Microsoft notify the outages via their Twitter account besides the Live Status website shared previously
https://twitter.com/xboxsupport?s=21&t=xtwh...

But you can receive a notification when the problem is fixed expanding the affected category in the live status website and you should be able to see a button that says "notify me"

Well I was never notified there was any kind of outtage. So that would have been nice to know before I deleted all my saved data

This is not the first time I've signed into my Microsoft account for minecraft or Nintendo switch. I have tried multiple wifi connections, and the only error code it gives me is error code 500 and says xbox live cannot complete this request. I am able to log into my Microsoft account on the regular Microsoft website, just doesn't work for the website to connect it to my minecraft for nintendo switch
