While Overcast now supports Microsoft personal accounts, you may still wish to use a tenant-bound account to access Overcast. The steps below will guide you through creating such an account.
Step 1: In the Azure Portal, click on "Azure Active Directory" and click on "Users and groups"
Step 2: Click on "All users" then on "New user" in the top menu bar.
Step 3: Fill in the information and create the desired user name.
Step 4: The user will get a login name similar to "firstname.lastname@example.org". This is the login you will use in Overcast to connect.
Step 5: Follow the instructions in the Authorizations for Overcast article to grant the necessary permissions to the user on the desired subscriptions.
Step 6: You can now sign in with the newly created user account in Overcast and access all the information for the added subscriptions.
