Can Meta Muse Access Outlook? Mail and Calendar (2026)
Yes. Muse has two Outlook connectors, Outlook Mail and Outlook Calendar. Muse describes Outlook Mail as a way to “manage and organize your inbox,” with access to “message content, attachments, sender info and metadata,” and it asks before taking actions it thinks need review.
Carly makes Outlook run the way Outlook people want it to. Every Outlook account you have, personal and work, plus shared mailboxes like support@, sorted into your categories and folders by fixed rules on every email. Carly files the attachments, logs client mail in your CRM, and updates Teams, OneDrive and the rest of your apps automatically.
Set it up in Muse
- Connect every Outlook account at carlyassistant.com/integrations: personal Outlook.com or Hotmail, each work account, and any shared mailbox you answer from.
- Paste the prompt below into Muse. It adds Carly as a custom connector and lists every mailbox and calendar it can see.
- When Muse asks for a key, open your Carly account page, click API keys, name the key “Muse”, leave every permission ticked and click Generate key. Paste it into Muse’s secure credential prompt, not the chat.
- Ask across all of them:
Check every Outlook inbox, including support@, for anything from the Riverside account and draft replies to what’s still open.
Carly setup prompt for Muse
Paste this into Muse. It adds Carly and walks you through connecting every Outlook account.
Help me set up Carly. I'll add it to you myself: tell me exactly what to click for the app you are, one step at a time, and wait for me to confirm before moving on. If you can do the setup yourself (Claude Code, Codex, Muse, Grok Bot), go ahead, and ask me for any key in your secure credential prompt, never in the chat. Once it's added, walk me through connecting my accounts, check it worked by listing every mailbox and calendar you can see through Carly, and ask what I want to hand off first. The steps are below.
# Connect Carly to an AI app
> Carly connects to thousands of apps, from Gmail, Outlook and calendars to Slack, HubSpot and QuickBooks, and keeps working after a chat is closed: answering email, booking meetings, following up and running workflows the moment something happens.
MCP server: https://carlyassistant.com/mcp/ (streamable HTTP, OAuth)
## Setup
1. Add the Carly plugin (some apps call it a connector):
- ChatGPT: open https://chatgpt.com/plugins/plugin_asdk_app_6a67a26316b88191860222f918d4ec54 (or open Plugins and search "Carly"), add it, and sign in.
- Claude (claude.ai, Claude Desktop, or Cowork): open https://claude.ai/directory/carly, click Connect, and sign in.
- Claude Code: `claude mcp add --transport http --scope user carly https://carlyassistant.com/mcp/`, then /mcp, pick carly, and authenticate.
- Codex: `codex mcp add carly --url https://carlyassistant.com/mcp/`, then `codex mcp login carly`.
- Cursor: add {"mcpServers": {"carly": {"url": "https://carlyassistant.com/mcp"}}} to ~/.cursor/mcp.json, then sign in to carly from Customize.
- Muse: a custom connector to https://carlyassistant.com/mcp/ with a Carly API key as its bearer token. The key comes from carlyassistant.com/account (API key under Carly) and goes in Muse's connector settings, not in a chat message.
- Grok: grok.com/connectors > New Connector > Custom, paste https://carlyassistant.com/mcp/, and sign in.
- Grok Bot: a custom remote MCP server named carly at https://carlyassistant.com/mcp. Approve it and sign in.
- Perplexity: Plugins in the sidebar (or Customize > Connectors), then Add custom > Connector > Add MCP connector. Choose Remote, name it Carly, paste https://carlyassistant.com/mcp/, pick OAuth, check the box and click Add, then click the Carly card to sign in.
- Anything else: a remote MCP server (streamable HTTP) named carly at https://carlyassistant.com/mcp/. It signs in with OAuth.
Sign in with a Carly account, or create one at carlyassistant.com.
2. Once it's added, Carly's tools show up in the chat. If they don't, turn Carly on for the chat or start a new chat.
3. Connect accounts at https://carlyassistant.com/integrations. Under Accounts, click Connect Google or Connect Microsoft, pick the account and grant everything it asks for. If the page shows an email field instead, type the address, click Add Email, click Connect Google or Connect Microsoft on the new address, then Connect with Google or Connect with Microsoft. For an address that is already connected, open Manage access and click Connect next to anything missing. Repeat for every account, then connect any other apps.
4. To check it worked, ask Carly to list every connected mailbox and calendar.
5. Something to hand off first: "Check all my inboxes for anything that needs a reply today."
## Business calls and texts
Business SMS, business phone calls, voicemail and a team's voice and text agents are a separate connector, Carly Teams, at https://carlyassistant.com/team/mcp. It needs membership of a Carly organization and its own connection. Its setup is https://carlyassistant.com/team/mcp.txt.Seeing “Need admin approval” when you connect a work account to Carly?

What Muse does with Outlook
Outlook was on the first list of connectors Meta’s Alexandr Wang published, next to Gmail and Google Calendar, and you decide “whether it can just read your data, or read and write it.” With Outlook connected, Muse can:
- Search and summarize your Outlook mail. “What did the auditor ask for last week?”
- Draft and send replies. Meta says Muse “checks with the person before sensitive actions like sending an email.”
- Organize the inbox when you ask, or when Muse decides something needs doing.
- Read and change your Outlook calendar through the separate Outlook Calendar connector.
Where it stops
It decides as it goes. Outlook’s strength is predictable organization: this sender gets this category, that subject goes to that folder. Muse is an agent, and its connect screen says so plainly: “Muse may take unexpected actions. Monitor it carefully.”
Mail and calendar are separate connectors. Outlook Mail and Outlook Calendar are each connected and permissioned on their own, and neither shares rules with your Gmail.
It asks before it acts on anything it thinks needs review. That keeps you safe, and it keeps you in the loop on every send.

What Outlook looks like with Carly
Carly works Outlook the way Outlook users already organize it: categories, folders and shared mailboxes, by rules that run the same way on every email. Turn these on from Muse once Carly is connected:
- Auto-label incoming email. Each new message gets one of the Outlook categories you already use.
- Triage and file every email. New mail moves into the folder it belongs in, and anything unclear stays put.
- Answer from the shared mailbox. A reply to a
support@email goes out fromsupport@, not from you. - File attachments automatically. Contracts and invoices land in the right folder the moment they arrive.
- Update your CRM. Every client email is logged on the right person in Carly’s CRM, Dynamics 365, HubSpot or Salesforce.
- Text me when an urgent email arrives. In any Outlook account, the moment it lands.
Carly also connects to Microsoft Teams, OneDrive and SharePoint, and thousands of other apps. See Carly for Outlook. Free Zapier-style workflows; AI agents from $35/month. Get started.

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."
