Using New Outlook on Windows for personal email, calendar, and contact management
Hello Colleen Meiring,
Thank you for your feedback, and we're really apologizing for the incorrect issue address, you are correct, it should be "I cannot add a new contact to People". However, did you try Microsoft Support and Recovery Assistant?
Anyway, can you try your account on a different device with different network, to make sure that the problem not related to your account, and if it's work on the other device, you have to clear your browser cache, and create a new profile for outlook by going to Control Panel > Mail > Show Profiles.
Click Add to create a new profile and configure your email account.
I hope this solution make your day, Let me know if this resolves your issue or if you need any further assistance!
Best regards,
