Document AzureAD Conditional Access Policies

Andres Bohren
Hi All, I had the “pleasure” again this week to Document the Azure AD Policies. Making several Screenshots in the Azure AD Portal seemed not the best way. MSGraph: List Conditional Access policies So tried to use the Microsoft Graph Explorer You need the Permission: Policy.Read.All https://graph.microsoft.com/v1.0/identity/conditionalAccess/policies While using the JSON could be one way. It’s not very good if you have to Document it in a Word Document right.

This year, we plan to disable these older TLS versions for POP3/IMAP4 clients to secure our customers and meet compliance requirements.
