Who it is for
Outlook users with heavy inboxes, including people who share a mailbox with colleagues.
Triage an Outlook inbox and draft replies
Overview
Outlook Email works against a connected Microsoft Outlook account. Mail can be sorted through, threads reduced to a summary, tasks lifted out of a conversation, and replies or forwards written as drafts.
A set of named skills ships with it, covering inbox triage, reply drafting, shared mailboxes, subscription cleanup, and task extraction. The declared capabilities are interactive and write, so composition happens through the app itself rather than only in the chat window.
The app is published by OpenAI and depends on the Microsoft Outlook connection being in place. That puts its reach at whatever the linked Microsoft 365 or Exchange mailbox contains.

Shared mailboxes and subscription cleanup get their own skills, which takes it past the usual summarize-and-reply pairing.
Availability
Outlook Email is listed in the ChatGPT apps directory only. OpenAI has no connector under the same domain in the Claude directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.
ChatGPT apps are built on MCP, and the same server can back a Claude connector, so the absence is a distribution decision rather than a technical one.
ChatGPT listing
Outlook Email declares 6 named skills, which puts it in the 6.7% of ChatGPT-listed apps that do.

This is an independent catalogue entry compiled by Node8 from Outlook Email's public marketplace listing as it stood in August 2026. Listing facts come from the marketplaces; the comparisons against the rest of the directory and any live-endpoint measurements are Node8's. Node8 is not affiliated with OpenAI, and inclusion here is not an endorsement.
Node8 builds MCP servers end to end: deciding which tools are worth exposing, the authentication and permission model, the review submissions, and the onboarding that gets them used. One server serves ChatGPT, Claude, and Microsoft Copilot.
