Hi Jeffrey,
I'm Ahmed and I am here & happy to help.
You can create two different Microsoft accounts on your computer, using your separate work and personal email addresses and passwords. That way, you can easily switch between the two accounts and keep your files and settings separate.
Please check this: How to separate work and home Office account on the same computer? >> https://answers.microsoft.com/en-us/msoffice/fo...
I hope this helps! Let me know if you have any further questions or concerns.
Best regards,
