Because of changes to Jira over the years, how we added customers to our service desk was done differently or incorrectly, resulting in customers who should have been portal only / email support being converted to Atlassian accounts. In an effort to clean up the accounts (removing terminated employees) so we can mass log out accounts to force the 2FA sign, we removed accounts that had no apps assigned.
As a result, we now do not have the ability to add the person back as a portal only user? It's insisting that we re-activate their Atlassian account, which they don't use..
