I am trying to change an email address to someone who is changing companies. They will not have an email address in our domain. When I try to add the email address to their company I get an error
“This email belongs to an organization that is not permitted to share access with your existing organization.”
Hi @James_Jancel, welcome to the Asana Community Forum!
To investigate this further, I’d recommend reaching directly to our support team who will be able to take a closer look into this for you! When reaching out, make sure to provide them with the following info, it will facilitate their investigations:
Sorry for not being able to resolve this specific issue via the forum. Unfortunately I don’t have the tools to have a closer look and verify the domains. If you have any other question in the future feel free to reach out here, in most cases we will be able to resolve your issue, and if not, we’ll be able to redirect you to the right place 
Sure, reach out to the “support team” but how long does it generally take for the support team to respond? I am going on day four with the above issue. For your reference, this is case #310972.
Thank you,
CR
