Connecting azure active directory to azure devops for authentication and authorization

Hi there,

I am trying to connect azure active directory to azure devops but it shows this error:

|””our organization DevopsLab-2023 failed to connect to the Default Directory Azure Active Directory.

User bmhitpro@gmail.com is a guest in the target AAD tenant Default Directory. The current organization policy does not allow guest users to access the organization. Change the policy setting to allow external guest access and try again.””

Can you please help?

Thank you
