Claude + Outlook: Add-in, Connector and Triggers (2026)
Yes. Add the Carly connector to Claude, connect Outlook, and you can set up triggers right from the chat: when an email lands, do that. “When a client emails an invoice, label it Billing, save the PDF and draft a reply.” You type it once in Claude. Carly runs it on every email, whether Claude is open or not.
Where Claude and Outlook fall short today
Claude reaches Outlook two ways: Anthropic’s Claude for Outlook add-in, and its Microsoft 365 connector. Here’s what people run into:
- The add-in never sends. Anthropic’s own docs say Claude for Outlook “never sends mail or invites on its own.” Every reply lands as an unsent draft, and it’s still a beta.
- Personal Outlook doesn’t work. The Microsoft 365 connector needs a work account. Anthropic says Outlook.com, Hotmail and Live addresses can’t be used.
- Sending depends on your org. The connector only sends email or changes your calendar if write tools have been turned on for your organization.
- Nothing happens when an email lands. A client’s invoice, a lead asking for a call, a newsletter cluttering the inbox: Claude waits for someone to open a chat.
How Carly fixes it
- It sends. Carly replies, follows up and sends invites from your own address, on your rules.
- Every account. Work, personal, Outlook.com and Gmail, shared mailboxes included, all in one place.
- It sorts everything. Carly labels and files every email as it arrives, the same way every time.
- Triggers. Carly acts the moment an email lands, and on any schedule you set.

Triggers you can set up from Claude
Type these into Claude. Each one becomes a trigger that runs in the cloud, the same way on every email, whether or not you’re in the chat:
- “When a client emails an invoice, label it Billing, save the PDF to OneDrive and draft a reply.”
- “Move every newsletter to Read Later and every cold pitch to Sales, across all my accounts.”
- “When a lead asks for a call, reply with three times from my calendar.”
- “When anything from my top ten clients lands, text me.”
- “When I flag an email, add it to my tasks and remind me Friday.”
- “If a prospect hasn’t replied in three days, send a follow-up from my Outlook.”
- “Every morning at 8, send me a digest of what came in overnight.”
Steps that don’t need AI run as free Zapier-style workflows. Carly connects to thousands of apps, so any of these can also update HubSpot, post to Slack or open a task in Asana.
Ask Claude about your Outlook email
Carly also lets Claude work your inbox in the chat:
- “What did Emily send me about the Adobe renewal?”
- “Draft replies to everything from clients this morning.”
- “Find every unpaid invoice across my Outlook accounts and list them.”
- “Find a time next week for Michael, Claire and me, and send the invite.”

How Claude connects to Outlook today
Without Carly, Claude reaches Outlook two ways, and each does a different job.
The Claude for Outlook add-in sits inside Outlook on the web, Windows and Mac. It’s a beta for Pro, Max, Team and Enterprise plans. It sorts your unread mail, sums up long threads, reads Word and Excel attachments, and drafts replies and invites. To add it, find Claude for Outlook on Microsoft AppSource, choose Get it now, open any email, click the Claude button and sign in. Every draft lands unsent, and you click Send. It doesn’t run in the Outlook mobile apps.
The Microsoft 365 connector lets Claude search your mail, calendar, OneDrive, SharePoint and Teams from a chat. It’s on every Claude plan but needs a work account. Connect it under Customize, then Connectors. A Microsoft Global Administrator has to approve it once, and on Team and Enterprise plans an organization Owner has to turn it on. Sending email takes write tools, which an admin has to enable, and attachments aren’t supported.
Neither one acts on its own. Both wait for you to ask.

See what people say
"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
