Hi @Morten Sørensen ,
Welcome to Q&A forum!
Unfortunately, this cannot be achieved based on the current settings. External sharing is mainly set at the tenant and site levels, and applies to all users in the tenant who have permission to perform external sharing (except for Allow only users in specific security groups to share externally, which restricts users). In other words, for your needs, allow all employees to share to a specific set of domains
and only a few employees to be able to share to all domains
are in conflict. For the former, you can set Limit external sharing by domain, which applies to all employees, so there is no way to achieve only a few employees to be able to share to all domains.
To address your concern about the situation, we’d suggest you go to feedback on this issue, this is the best platform to let us hear from you and make our products and services better for you and others.
Good day!
