Hello,
I am unable to invite a new user - this user never used any Jira account using this email, not in our list. But I am still getting this error, not able to invite.
------
we’re unable to invite users at least one user has an account that is deactivated or suspended. only an organization admin can restore their access. if the account doesn’t exist in your organization, contact support.
------
Please, let us know what can be done. Thank you!
This discussion brings a similar problem, but there is no resolution for those who never used an email and still get this message.
