Some colleagues appear Deactivated right after an invite, they can't access the Jira site I created either after they log in with the allowed domain fcc.es
The thing is I was able to invite two other guys also with domain fcc.es, but there are a few more that will consistently appear as Deactivated. I have tried deleting those users, resending the invites, ...
Those users never worked with Atlassian tools before, so this has nothing to do with previous usage in other projects/companies.
None of the users (the ones that successfully joined, or the ones that failed) appear in Managed accounts, so I cannot reactivate them over there. My corporate IT says they do not manage them either (FCC company, Madrid, Spain).
Please advice, as the site is already holding test info that I should be sharing with my whole team.
