How do I automatically categorize calendar meetings in new Outlook?

Hi @Ashleigh Price, 

Thank you for posting your question to the Microsoft Q&A forum. 

By default, Outlook rules are designed to perform actions with emails only, meetings cannot be controlled using Outlook rules. 

According to your concern, to categorize meetings in Outlook, I would recommend using Power Automate. To categorize a meeting with title and particular people, please perform these steps: 

1. In Power Automate, select Create > Automated cloud flows. 

2. Name the flow then select When an event is added, updated or deleted (V3) event. 

3. Select Create. 
4. Select the calendar where the meeting flows into. 

5. Click the New step button, search Condition. 

6. For the True branch, add Send an HTTP request action:  

• Enter in the URI as below.

https://graph.microsoft.com/v1.0/me/events/@{triggerOutputs()?['body/id']}

• Select the PATCH method. 
• Enter {"categories": ["blue time"]} in the body. 

7. Select Save, then ask someone to create a meeting and add you add a participant. 
8. Your meeting will be categorized as a blue time category.
