@[deleted] I can confirm that in version 1.10 unless an agent has been granted Extended Access to a department in Admin Panel > Agents > > Access > Extended Access, that you cannot assign a ticket to that agent from another department.Prior to 1.10, when you went to assign a ticket to an agent, the entire agent directory was visible, and an agent could get direct ticket assignment to a ticket for a department for which he normally did not have access. This was a handy feature for us as well for when we needed to get help from someone outside our normal department structure, without having to extend access to the department. The agent could see and address the single ticket from the other department without needing to see every ticket from that department.For now we extend access, assign the ticket, then remove the extended access.
