Greetings.
We have a bed of ~600 customer users and in an attempt to administer dormant accounts we performed an audit suspending accounts with no activity (Activity Date) within 60-days and with a Status of "Invited" within https://admin.atlassian.com/.
The presumption was that these are accounts that have received the invitation but have not interacted with the platform since that last Activity Date.
We received reports from some of the customer accounts we suspended, that the activity date and the Status reflected in https://admin.atlassian.com/ do not reflect the status of their accounts. They are interacting with the portal to submit tickets under their account logins. Reading on the forums it would appear this should have flipped the accounts off of Invited status.
We've re-granted the access to move of the impacted users, however we now have a gap in platform administration. We still have a mass of customer accounts that appear to be inactive based on Status and Activity Date.
What is Activity Date measuring, what kicks an update to the https://admin.atlassian.com/ portal?
How do you (as JIRA Admins) accurately isolate customer user accounts with truly dormant activity?
