We have a user who used to have Jira Product access and was able to comment on issues. However this user's Jira product access has been removed as well as any access to any Jira groups or Project roles. This users email details however is still able to appear (on issues which the users made comments before) when the users name is being tagged in the comments section.
How can we prevent users who no longer has product access to Jira (but still have access to Confluence thru Atlassian Guard) from being tagged in the comments section.
regards,
