With little effort, you can expose such an agent to team members and colleagues though something like Slack and enable a company-wide productivity booster.\n\n### How it works\n* A Slack Trigger node is configured to catch \"bot mentions\" events in a designated channel.\n* The message is parsed using the Edit fields node to extract only the required attributes of the event.\n* An AI Agent equipped with Outlook Calendar Tools enables question and answer capability for the organisation's shared calendars and events.\n* The AI agent's response is sent back to Slack as a reply to the user's query.\n\n### How to use\n* The workflow is triggered via @mention-ing the bot followed by the query. eg. \"@bot how many meetings does Paul have to attend to this week?\"\n* To start listening to real mentions, you must activate the workflow and set it to production mode. You must use the production webhook URL for the event subscription.\n\n\n### Need Help?\nJoin the [Discord](https://discord.com/invite/XPKeKXeB7d) or ask in the [Forum](https://community.n8n.io/)!"}, "typeVersion": 1}, {"id": "03083765-b3bb-42f6-8f30-7087687bc6eb", "name": "Send Reply", "type": "n8n-nodes-base.slack", "position": [620, -180], "webhookId": "68154e10-0b98-4d18-816c-2af8ab954694", "parameters": {"text": "={{ $json.output }}", "select": "channel", "channelId": {"__rl": true, "mode": "id", "value": "={{ $('Get Message').item.json.channel }}"}, "otherOptions": {"thread_ts": {"replyValues": {"thread_ts": "={{ $('Get Message').item.json.ts }}"}}, "includeLinkToWorkflow": false}}, "credentials": {"slackApi": {"id": "VfK3js0YdqBdQLGP", "name": "Slack account"}}, "typeVersion": 2.3}, {"id": "19c8e68b-2bf1-403a-a43d-cdc465233436", "name": "Respond to Challenge", "type": "n8n-nodes-base.respondToWebhook", "position": [-240, -440], "parameters": {"options": {}, "respondWith": "text", "responseBody": "={{ $json.body.challenge }}"}, "typeVersion": 1.1}, {"id": "2b9f7d68-8e76-440b-9a8b-b9eb4fc7061c", "name": "Is Auth Challenge?", "type": "n8n-nodes-base.if", "position": [-520, -300], "parameters": {"options": {}, "conditions": {"options": {"version": 2, "leftValue": "", "caseSensitive": true, "typeValidation": "strict"}, "combinator": "and", "conditions": [{"id": "cd56f5f2-dbb8-4cf0-83c8-f0566510ff51", "operator": {"type": "string", "operation": "exists", "singleValue": true}, "leftValue": "={{ $json.body.challenge }}", "rightValue": ""}]}}, "typeVersion": 2.2}, {"id": "c91350ef-5701-4188-8b1f-de12a0076a56", "name": "Get Message", "type": "n8n-nodes-base.set", "position": [-240, -180], "parameters": {"options": {}, "assignments": {"assignments": [{"id": "44da9c3a-35eb-4636-9483-65492e858d96", "name": "ts", "type": "string", "value": "={{ $json.body.event.ts }}"}, {"id": "761840aa-d2e3-4345-95bb-e7866b755880", "name": "message", "type": "string", "value": "={{ $json.body.event.text }}"}, {"id": "094457fc-c149-4175-bed2-f0906cb70dea", "name": "is_bot", "type": "boolean", "value": "={{ $json.body.authorizations[0].is_bot }}"}, {"id": "baf91a59-88fa-45fc-bfcb-ff27d0fe397d", "name": "user", "type": "string", "value": "={{ $json.body.event.user }}"}, {"id": "abc6c16e-50e2-4154-9db9-4e12f9009d01", "name": "channel", "type": "string", "value": "={{ $json.body.event.channel }}"}]}}, "typeVersion": 3.4}, {"id": "0681782d-21f3-4130-809c-188d83ebb7a9", "name": "On BOT/APP Mention", "type": "n8n-nodes-base.webhook", "position": [-800, -300], "webhookId": "c63b08ce-360d-4185-aae1-294afef5cf2b", "parameters": {"path": "c63b08ce-360d-4185-aae1-294afef5cf2b", "options": {}, "httpMethod": "POST", "responseMode": "responseNode"}, "typeVersion": 2}, {"id": "d0b12a70-e3e8-4149-98ba-dc2cf01f9953", "name": "Sticky Note1", "type": "n8n-nodes-base.stickyNote", "position": [-800, -520], "parameters": {"color": 7, "width": 380, "height": 180, "content": "## 1.
