The decision
Should ChatGPT for Outlook make your shortlist?
Start with the job, the team, and the constraints. Product fit becomes much clearer when those three line up.
Practical use cases
Jobs it can take on
- Summarize an email in the Outlook add-in panel
- Draft or append content while composing an email
- Categorize, flag, move, or mark an email as spam based on its content
Before you choose
Know the tradeoffs
- ChatGPT features require a separately billed OpenAI API account and API key.
- The add-in requires Outlook with a Microsoft email account to install AppSource add-ins.
- In the new Outlook for Windows, the add-in works only on the primary account when multiple accounts are configured.
Inside the product
What you can actually do with it.
The core product capabilities, grouped around the work they enable.
Custom prompt configurations
Users can build multiple configurations with their own prompts, conditions, display preferences, and manual or automatic triggers.
Read and compose modes
Configurations can analyze received email or assist while users write a new message.
Email actions
A configuration can return written output or perform actions including categorizing, flagging, moving, or marking an email as spam.
Typical workflow
Download the add-in manifest, install it through Outlook's add-in controls, and open it from the Outlook ribbon or reading pane. Add an OpenAI API key, then create configurations that define the email content to process, the prompt, and whether the action runs automatically or from a button. The output appears in the add-in panel or can be written into a message.
