Missing "Create One!" (sign up) link when using Azure for OpenID

Question

I have configured Azure as an IdP in ServiceNow. This works fine, but usually when a user gets the page to sign in, they also have an option to sign up for a new account. This is currently missing when I test mine.
I am not sure where this needs to be configure. Please help!

Answer 1

Is it possible that the external users who did not get the option to create a new Microsoft account received the invitation on their Microsoft accounts/IDs already?

The option to create a new Microsoft account depends on the account from which the user has accepted the invitation. If an external user receives an invitation while on a Microsoft account, such as Outlook, Hotmail, or Live.com, the user will not get the option to create a new account because the user is already accepting the invitation from a Microsoft account.

One option would be to directly send them the link to create the account. https://account.microsoft.com/account?lang=en-hk
