Q: How do I get M365 Email and Calendaring to stop prompting me for my username and password constantly on Windows 10?

If you're repeatedly prompted for your username and password, you may need to run a registry file to update your configuration.

1. Run the registry file: MSOAuthForAutodiscover.reg
2. Restart your email client.
