Remote Desktop Microsoft account

I was using a Local User Account on my PC, but I kept getting "Microsoft Account Problem " and OneDrive Not Connected" notifications on startup (all PC sharing is turned off), so I switched to Login with Microsoft Account instead. Then I could not make a Remote Desktop connection to the PC, even in my house on the same network (I usually connect through a VPN). I tried RDP connection with Microsoft credentials, Microsoft PIN, short User Account name, full name - no combination was accepted. Changing back to a local account fixed RDP right away, but brought back the frequent notifications.
It looks like this has come up for a long time. Is anyone aware of a solution? And with a local user account (my Microsoft account IS listed under "accounts used by other apps"), why do I keep getting notifications of Microsoft account problems?
