I've created several Apps in Azure Active Directory and some of them I don't need anymore. I want to remove them but the remove icon at the bottom is greyed out. Does anyone know what the reason for this could be or if there is another way to remove the Apps I don't need?
If the applications are multi tenant, first thing you would need to do is to change that so that they are not multi tenant. Then you should be able to remove the applications from your Azure AD.
