Can I invite someone with an organization email address as a guest on a project? This would be if we have contractors or subcontractors that will be with us for a limited time and for only one project but would still have an internal email address
If this relates to enabling folks who are members of your Organization to collaborate on a Project/Task in a hidden space(Team/Project/Task) then they can be invited to do so according to how much access you’re looking to grant them.
If you wish to add them to just a Task, add them as a Follower to that/those Task(s).
If you wish to add them as a Guest to just a Project, add them as a Project Member.
Additional information on Guests is available at the following link to the guide on the subject.
Hope this helps!
