At our company, when someone leaves, their email is generally forwarded to someone else. We disable them in Jira by removing them from all groups and removing their application access to Jira and Confluence.
But it seems this doesn't stop Confluence from sending out Recommended emails per it's schedule to that user.
I worked around it by re-enabling the user temporarily, going to their Confluence profile and disabling all the notifications, then disabling all the user again.
But it doesn't make sense to me why a disabled user would still be getting emails.
Am I missing something?
