A difficult ticket gets solved and the answer stays inside that one thread. Weeks later the same problem arrives from a different customer, and whoever picks it up starts again from the beginning.
Ask your agent to turn the solved conversation into a guide the next person can follow.
What the agent starts with
Ticket #4402 sits in Closed on the Support board. A customer had stopped receiving any email from us at all, and the conversation runs to seven messages, two of them internal notes.
How the answer was reached is the part worth keeping. Support checked spam and quarantine, then checked the customer's notification settings, then sent a test message that never arrived and never bounced, and escalated it as a fault on our side. Engineering found nothing. The cause was the customer's own mail server, which had been holding messages silently since we moved to a new sending domain earlier that month.
The same problem is open in Queue again now, from someone else.
The prompt
Asking for the dead ends is the difference between a guide and a note to self. Anyone meeting this problem again will reach for the spam folder and the notification settings first, and the guide can tell them not to bother.
What comes back
A goal on the Support playbook board holds a guide in four sections: the symptom in the customer's words, how to tell this apart from the problems it resembles, the fix as numbered steps, and what was ruled out. It is filed under the symptom rather than the cause, called something close to "customer says they have stopped receiving any email", because that is what a person types into search when it happens again.
