Cannot add people who are not in my domain

[admin]

Hi, I send invitations to join to people who are in my domain (e.g. mydomain.com).  But I cannot add people who are partnerdomain.com.  I get the message below that a person is not found.

This is for Jira and Confluence. 

Thanks.

Any chance you are using Access to manage logins? Maybe you are trying to bring users from an active directory that clearly won't have external users

I am using G Suite.

Last time I checked to have that integration you must have access, it can't be done straight from Jira. Maybe you need to add the user there first, it's not the tool I use the most.
