It is stating that the user we are attempting to assign it to is not an agent and that the agent is disabled (a bit contradictory).
We're actually not trying to assign it to a user, but a mail-enabled security group. The mail-enabled security group is set as an agent in our contacts list, and it is set as active.
This was previously working with no issues until this week. Am I doing something wrong? Is there a better approach to this? Any help would be greatly appreciated, thanks in advance.
