Some colleagues appear Deactivated right after an invite

[Alfonso Moreno Rey]

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.

Hello @Alfonso Moreno Rey 

That usually points more to the state of those specific Atlassian accounts than to a general problem with your site.

Because you mentioned you are on Jira Cloud Free and acting as Product Admin, there is also a chance this is happening outside the site-level admin scope.

A few questions that would help narrow it down:

Do the affected users already have an Atlassian account with that same email address?

Can one of those affected users log in directly to their Atlassian account outside your Jira site?

Are all affected users from the same email domain, and are the working users from that exact same domain too?

Has your company ever had another Atlassian organization, admin, or central account management for those users?

Do those users appear as deactivated only when you try to invite them, or do they already show that status somewhere else as well?

Are the affected users former employees, renamed accounts, or reused email addresses?
