Visitor

In Microsoft 365 -> Azure -> External collaboration settings, for the Collaboration Restrictions setting I have it set to "Allow invitations only to the specified domains (most restrictive)".

 

I now need to add a specific gmail user, (let's say testuser@gmail.com), as a guest to the organization, but in order to do this I need to add "gmail.com" as a whitelisted domain. If I do this, it kind of defeats the purpose of using an allow list since there are millions of gmail.com accounts that exist.

 

I am wondering if there is a way to specify gmail.com in the allow list, and then create another restriction for all gmail.com emails where the email must be in a list that I specify? So basically I would have a policy that says for all gmail.com users, only allow testuser@gmail.com, otherwise block.

 

Is this possible via conditional access or other means?
