Question about Microsoft Office Home 2024

What worked:
Make sure there’s no MS Teams running/installed (this automatically associates you having the MS 365 license key). With MS Teams, it will not recognize/link/activate the license key for MS Office 2024.

After several hours trying to fix the issues (no license key found, unable to connect, can’t activate, read only mode, etc.), the culprit was in fact MS Teams.

Have you entered the licence key you received with the product?
