About Domain Restrictions in Zoom Rooms

Q:

When hosting a conference in Zoom Rooms, is it possible to restrict the domain of participants? Is it possible 
to host a conference with zoom rooms that has the main setting and invite people outside the domain in exceptional cases?

A:

If Zoom Rooms is the organizer, in the account settings

“Only people signed in as users with specific domains can attend meetings.”

It becomes effective only when the setting is ” ON + Lock “.

It is impossible to apply domain restrictions etc. individually to Zoom Rooms.

The pattern in which Zoom Rooms is the moderator is recognition that you can not meet the requirements (excepty you want to invite people outside the domain).
