Hi @Andre Brouwer , if the "Save" button is greyed out when you try to disable Security Defaults in Azure AD, it's likely because there are some required settings that have not been configured yet. Here are a few things you can check:
- Make sure that all the required settings have been configured. To disable Security Defaults, you need to configure the following settings:
- All users must have a valid mobile phone number in their profile.
- All users must have a valid alternative email address in their profile.
- All users must be enrolled in Azure AD Multi-Factor Authentication (MFA).
- If any of these settings are missing or incomplete, the "Save" button will be greyed out.
- Check if there are any conditional access policies that require MFA. If there are any conditional access policies that require MFA, you will not be able to disable Security Defaults until those policies are updated.
- Make sure that you have the necessary permissions to modify the Security Defaults settings. As a global administrator, you should have the necessary permissions, but it's possible that your permissions have been restricted by another administrator.
Please let me know if you have any questions and I can help you further.
