Howto add Azure AD as AWS Cognito Federated IdP
The steps are quite long, but I've created a tutorial on setting this up.There is a current bug within the AzureAD web console that prevents changing the App ID to a URN, but it can be worked around by modifying the parameter with AzureAD powershell.
See the following blog post here:

I ran into some troubles while logging in via personal live/hotmail accounts using SAML, turns out there's no proper support for that yet, try OIDC.
