Question:

What could be the reason that the flag on a user is set to false without modification by us? It happened a few times to the same user after we enabled it again. In the last days.

Answer:

It means the last time the Helpdesk app tried sending a message to this user, we received a bounce response from their email server, that started with "5xx" meaning the failure is permanent.

Those bounced responses are usually shown next to replies you tried sending to the user.
