If we don't renew our help desk agent licenses that are up for renewal, I'm sure you get one administrator help desk license built-in, so you can still access your tickets via that one account? Is that correct?
Hello, Users that are not an agent, will lose the agent permissions. So they won't have access to the tickets any longer. But if you still have one account to which you can grant the agent permissions, he should be able to see the tickets.
