Live getting you down?

Sometimes Single Sign On gets somewhat confused,
Doesn't seem to care about the work account used.
If your work account and live account are somehow the same,
Authentication can break due to having a split brain.

You see, in the cloud you need one source to authenticate.

If housed in two sources, the account becomes desiccate.

For the portal doesn't know which source to talk to,

So it shrugs its shoulders and says, "I don't know you".

So to check if your work account, is also MSA/Live,

A powershell command will help you to thrive.

Just copy and pace the command from below,

put in the work SMTP address, and let the result flow.

ConvertFrom-Json (Invoke-WebRequest -Uri "https://login.microsoftonline.com/common/userrealm?user=SMTPADDRESS&api-version=2.1&checkForMicrosoftAccount=true" -UseBasicParsing) 

If the return for MicrosoftAccount turns out to be Zero,

then the account is a Live Account, you've found it you Hero.

The live account needs to be changed to something else,

Then you can watch as the issue quietly and quickly melts.

For when the work account, no longer serves more than one master,

Single sign on should work, avoiding confusion, delay and disaster.

Finding a way to change the live account becomes paramount,
