An integrated threat protection solution designed to detect, investigate, and respond to cyber threats across Microsoft 365 services.
Hi,
Thank you for sharing your question. I understand how frustrating it can be when one account works normally while another can open files but cannot edit or create documents.
It makes sense to be concerned, especially when everything is newly set up and you expect all users to have the same experience.
This behavior typically occurs when Microsoft 365 isn’t fully activated for that specific Windows user account. Each local or standard user profile must sign in with a valid Microsoft 365 license for editing features to unlock, and if the account isn’t properly activated, the apps may open in read‑only or unlicensed mode. Ensuring the affected user signs in with a licensed account, checking the activation status in any Office app, or repairing the Microsoft 365 installation can usually resolve the issue. If your subscription allows multiple devices or users, confirming the license assignment in the Microsoft account or Microsoft 365 admin center can also help.
May I ask whether the user account that can’t edit files is signed in with a Microsoft 365‑licensed email within Word or Excel, or does it show an activation or subscription warning?
Please feel free to share what you find, and I’d be happy to guide you through the next steps to ensure all users can fully use Microsoft 365 on the device.
I hope this helps.
Best Regards,
Noel
