How to login to network share when Microsoft Account is tied to windows login?

You must use MicrosoftAccount\[email protected] (this MicrosoftAccount prefix is important) as username. Now enter your Microsoft account password into the password box.

Try disabling PIN login for the Microsoft Account (Settings > Accounts > Sign in options > PIN). Windows rejected my credentials until I removed the PIN, then I could sign in just using my email address.

Figured it out. I was able to access a network share using my Microsoft account. This is the format:

• Username: email address tied to your account
• Password: password that you use to login to your Microsoft account online. Not the PIN

I created a local "dummy" account with admin privileges and use it only as a login for sharing.

If you used Microsoft Authenticato‪r when you log in to Microsoft Account and use PIN to unlock your PC, switching to local account and logging in to Microsoft Account again using your password may fix the problem. You can just use the password and ID of Microsoft Account for SMB.
