invalid license please contact administrator in MS Defender

Question

invalid license please contact administrator in MS Defender

Deepankar Arun Jain 0 Microsoft Employee

I have a personal M365 Subscription, for one of my account, I am not able to sign in to MS Defender app and it shows invalid license please contact administrator. I have validated properly that I have an M365 Personal Subscription User's image

Only for this one particular email, it says to contact administrator, meanwhile I have validated that the person is also shown in my family.

If possible whoever helping can share their microsoft alias to help?

Thanks

I have already reinstalled the app twice on my phone and even cleared cache, I have even tried to remove the email from family group and then readded it. It isn't working still.

Hello Deepankar Arun Jain

Thank you for the details. Since the Microsoft 365 Family subscription is active, this message is more likely related to how the Microsoft Defender app is recognizing the account on the Android device, rather than the subscription itself.

Please try the following:

Make sure Microsoft Defender is installed and opened from the Personal profile on the Android device, not a Work profile.
Sign out of Microsoft Defender, then sign back in using the same personal Microsoft account that is included in the Microsoft 365 Family subscription.
If any work or school account is connected on the device, try removing it temporarily and then test Microsoft Defender again.

If the app still shows “invalid license” after these checks, the best next step would be to contact Microsoft Support for further assistance on this issue. Here is how to contact them:

Open a website link - Contact - Microsoft Support
In the box below "We're here to help", type Microsoft 365, click "Get Help", and then click "Contact Support" below.
In this section, you will need to sign in to your Microsoft account.
Select "Microsoft 365 and Office" under Products & Services, select "Technical Support" as the category, and click to confirm
You can select " Chat with a support agent in your web browser " to access the chat window.

I hope you can get the support you need, have a nice day.
