Azure App Service is a service used to create and deploy scalable, mission-critical web apps.
Hi @Daniel Wilson ,
Based on the errors you’re seeing, I would first check whether the sign-in is being redirected to the Microsoft Services tenant rather than to a tenant associated with your Azure subscription.
The Selected user account does not exist in tenant 'Microsoft Services' message generally indicates that the account being used is not a user in that tenant. Similar cases have been reported when signing in with a personal Microsoft account.
I would suggest trying the following:
Open an InPrivate/Incognito window and go directly through the official Azure account sign-up flow.
Sign in with the Microsoft account you want to use for Azure.
If you already have an Azure directory, check Azure portal → Microsoft Entra ID → Overview and verify that you are working in the expected directory.
If you have multiple Microsoft accounts, make sure the browser is not automatically selecting a different account.
If the “You are not eligible for an Azure subscription” message continues to appear, the issue may be related to Azure subscription eligibility rather than the tenant error. In that case, I would recommend contacting Azure Support so they can check the account's eligibility and signup status.
I would avoid trying to add your personal account as an external user to the Microsoft Services tenant. If this is simply the default tenant being selected during sign-in, the better approach is to make sure you are signing into your own Azure directory/subscription instead.
If you can provide the exact error message (including the error code) and whether you are using a personal Microsoft account or a work/school account, we can narrow down which of these cases applies.
