Office 365 Access Troubleshooting on Win 10

I've recently added a new profile to my Windows 10 computer, and now I'm encountering issues when attempting to access Office 365. When I try to log in, it keeps giving me an error related to my password reset not being properly set up. Since I am the sole user and don't have an administrator for Office 365, I'm unable to rectify this on my own.

Key Tasks:
- Troubleshoot the issue causing the password reset error
- Assist in setting up the password reset correctly
- Ensure smooth access to Office 365 from all profiles on my Win 10 computer

Ideal Freelancer:
- Proficient in Microsoft Office 365
- Skilled in Windows 10 profile management
- Experience in troubleshooting access and permissions issues
- Excellent communication skills to guide me through the resolution
- Ability to secure and set up password reset correctly without an existing administrator
