A Smarter Inbox Built for Legal Work: The New :Harvey: for Outlook
The only legal AI platform that searches your full inbox, so you can draft replies faster and know what needs attention first.
A lawyer's inbox holds more than messages. It holds a client's last update, a redline from opposing counsel, a vendor contract request, the full history of a matter, and more. Making sense of it all takes time every day, whether you're an associate managing a full caseload or in-house counsel fielding requests from every corner of the business.
That's why we're introducing a new upgrade to Harvey for Outlook.
It is the first legal AI platform to bring full agentic power into your inbox, with the same reasoning and legal-specific grounding behind Harvey's web app and Harvey for Word.
A typical AI tool can only work with what you put in front of it: the pasted text, the named file, the precisely worded question. An agentic inbox means Harvey can take a broader set of instructions and decide on its own what's needed and where to find answers. Tell Harvey what you need — a drafted reply, all files related to a matter, a sense of what's urgent — and it goes to work across your inbox to assist you.
Draft and Revise Emails Without Leaving Outlook
Drafting a polished email reply takes time; Harvey for Outlook handles the heavy lifting for you. It grounds each reply in the matter, keeping you in control of every send, and matching how each client likes to hear from you — right where you already work.
Draft replies grounded in the matter
No more starting from a blank email or writing from memory. Harvey quickly drafts and revises a reply for you directly inside Outlook, grounded in your selected Vault documents and correspondences for the matter.
Stay in control of every send
Harvey never sends an email on its own. Every draft is written for you to review, and nothing goes out until you send it yourself. Additionally, if you ask Harvey for Outlook to revise a draft, the edits come back redlined, so you see exactly what’s changed before you send it.
Match client communication preferences with saved prompts
One client wants quick, direct updates; another expects detailed breakdowns. Now you can save how each client prefers to be communicated with as prompts, and every future draft will automatically follow their preferred communication style.
Search Your Entire Inbox, Get the Right Answer
Client instructions, negotiation history, and internal decisions all live somewhere in an inbox, and finding the right one gets harder as a matter progresses. When full inbox search is turned on, Harvey for Outlook makes getting answers from within your inbox as easy as asking a question.*
Search using plain language
Searching an inbox usually means knowing exactly the right keywords to use to find a specific email. Now you can ask Harvey for Outlook a direct question on a matter, in plain language, and it searches your entire inbox for the correct answer.
Get an answer backed by a citation
To provide a correct answer, Harvey reasons across every email in your inbox to find the one that answers your question, then returns it with a citation to the exact source. That way, you can verify the answer yourself instead of relying on memory or a guess.
Know What Needs Attention First
With thousands of emails in an inbox, there's no reliable way to know what actually needs a response first. Harvey for Outlook changes what "first" means. When full inbox search is turned on, Harvey reasons across your entire inbox — surfacing things like a court filing due today, a closing condition still outstanding, or a client waiting on an answer — so lawyers can start each day oriented to what needs their attention most.*
One Platform, Everywhere You Work
The improved Harvey for Outlook runs on the same platform as Harvey's web app and Harvey for Word, so you get the same reasoning and legal-specific grounding no matter where you're working. It's part of a larger effort to bring Harvey's agentic depth into the Microsoft tools lawyers already live in, alongside our recent updates to Harvey for Word and Harvey's integration with Microsoft Copilot and Copilot Cowork.
What Legal Teams are Saying About Harvey for Outlook
“We didn't want to run five different AI tools just to cover every use case. Being able to search email directly through Harvey for Outlook, without a separate purchase or license, solved a real gap for us. Before this, I would have to guess the exact words that were probably in an email — and sometimes that worked, sometimes it didn't. Now I can just describe what I'm looking for, and Harvey finds it.”

“The ability to search within Harvey for Outlook itself for related emails and context has been genuinely game-changing for our team. I used it with no advanced setup, just asking what topics and documents I'd been working on with a colleague. It came back with everything organized by topic without me asking for that. That's when it became clear to me that this would change how we approach a matter from the start.”
