Hello SEAN WHIFFEN,
The email shown (@igloos.cc) appears to be a work or school domain, so this could be one of two situations:
If this is a work or school account (provided by an employer or institution): You would need to contact your organization's IT administrator directly to reset your credentials.
If this is a personal Microsoft account that was set up using your work email as the sign-in address: Start with the Sign-in Helper tool which can identify and guide you through the issue: https://aka.ms/sign-in-helper
If the Sign-in Helper doesn't resolve it, submit an account recovery request here: https://account.live.com/acsr
