How to Use the Outlook Contacts Connector in Muse

1. What is the short answer?

As of October 25, 2026, Outlook Contacts is a live connector in Muse. It has been live since launch day, September 8, 2026, and it was still listed in the October 15 check, which counted 54 connectors in the web app. It connects your Microsoft address book to Muse, so Muse can look up the people you already saved and use their details when you write, plan, or follow up. It is the Microsoft alternative to Google Contacts: same job, different address book. If your work lives in Microsoft 365, this is the contacts connector to use.

Here is the honest version. The Outlook Contacts connector is not flashy, and that is exactly why it matters. Most Muse mistakes about people are not reasoning mistakes. They are identity mistakes: the wrong Sarah, the old email address, a phone number from three jobs ago. A connected address book fixes the identity layer first, and everything Muse does with people gets better after that. The rest of this guide covers how to connect it, what Muse can actually look up, the uses that are worth your time, and the limits to know before you lean on it.

2. What do you need?

• Muse access. You need an account with access first, in the United States, Canada, or Japan, where Muse has launched.
• A Microsoft account with contacts saved. The connector reads the address book in the Microsoft account you sign in with. If your contacts live in a different Microsoft account, sign in with that one.
• Your Microsoft sign in. You connect with your Microsoft account, the same way you sign in to Outlook itself. Work accounts may ask for an extra approval from your IT admin.
• Outlook Mail connected, or at least planned. Contacts on their own answer who someone is. Contacts plus Mail answer who someone is and what you last said to them. Our Outlook Mail connector guide covers that half.
• Approvals set to ask me. Before you connect anything, set approvals so nothing is sent without your tap. This matters here because contact details flow straight into drafts.

3. How do you connect it?

The connection itself takes a few minutes. The setup around it matters more, so run the steps in order and do not skip the approvals step at the end. Our complete connectors list keeps the dated status of all 54 live connectors in the web app, plus the 18 announced but not live, so check there if a connector you expect is missing from your account.

1. Open Muse and go to Settings. The connectors list lives there. What is printed there is what your account has, because rollout is staged and two accounts can see different lists on the same day.
2. Find Outlook Contacts in the connectors list and open it. If Outlook Contacts is not listed, your account has not received it yet. There is nothing to install and nothing you broke. Check again in a few days.
3. Sign in with Microsoft. Use the Microsoft account that holds the contacts you actually use. This is the address book Muse will see, so sign in with the right one the first time.
4. Grant the access Muse asks for. Muse needs permission to read your contacts. Read the permission screen before you accept it. If a scope surprises you, stop and check what it covers before continuing. Work accounts may also need your IT admin to allow the connection, and that is normal.
5. Set approvals to ask me. In Muse settings, set approvals so that sending email or messages always waits for you. Contact details are personal, and a draft that uses the wrong address is a message sent to the wrong person.
6. Test with a lookup you can verify. Ask Muse for the email address of someone you know well. Check the answer against your contacts. If it matches, the connection is good.
7. Use it for lookups first. Ask who people are and what details you saved for them before you ask Muse to draft anything to them. Once lookups are right, the drafts built on them will be right too.

Copy this prompt

You are my contact lookup assistant. Use my Outlook Contacts connector only.
Rules: you never send an email or message without my explicit approval. You look up people, show me what you found, and draft. I approve every send.
When I name a person, look them up in my contacts first. If there are two people with the same first name, stop and ask me which one I mean. Never guess between two contacts.
If a person is not in my contacts, say so plainly. Do not invent an email address or a phone number.
Now do this.
1. Look up [person name] and show me the email address, phone number, company, and any notes I saved for them.
2. Draft a short message to them in my voice about [topic]. Show me the draft. Do not send anything.
3. Tell me if the contact details look old or incomplete, and what is missing.

4. What can you do with it?

The connector earns its place with six uses. Everything else is a variation on one of them. None of them is dramatic on its own. Together they remove the small friction that makes writing to people feel like admin work. If you have used the Google Contacts connector, these will feel familiar, because the job is the same. The address book is different. The habits are the same.

Find the right person, by first name

Ask Muse for Sarah and get the Sarah you mean, with the email address and phone number you saved for her. This sounds trivial until you have three people called James in your address book and a draft addressed to the wrong one. The rule to set in your prompt is simple: when two contacts share a first name, Muse stops and asks which one you mean. Never let it guess between two people. A guessed contact is a message sent to a stranger, and a stranger reading your message is the one mistake in this guide that you cannot undo with an apology. The lookup habit also saves the five minutes you used to spend opening your contacts app, searching, copying an address, and pasting it into a draft. Five minutes, ten times a day, is most of an hour. That hour is what this connector gives back.

Draft to the right address, first time

Once Muse knows who you mean, the draft it writes uses the address you saved, not the one it half remembers from an old thread. Tell Muse who the message is for and what it should say, and the draft arrives addressed correctly. This is the use that pairs best with Outlook Mail: contacts supply the who, mail supplies the what you last said to each other. Our Outlook Mail connector guide covers the mail half, and our personal CRM guide shows how the two together become a lightweight system for keeping track of people. Read every draft before you approve it, and check the address line first. The body of a draft can be fixed in seconds. The address line decides who reads it. In a work inbox this matters twice as much, because a careless reply can reach a client, a manager, or a whole team, and you cannot unsend the impression it leaves.

Prep before a call or meeting

Before a call, ask Muse who this person is from your contacts: their company, their role if you saved it, and any notes you kept about them. Then ask what you last emailed them, if Outlook Mail is connected, and when you next meet them, if Outlook Calendar is connected. You walk into the call knowing who they are and where the conversation left off, instead of scrolling through old threads while they wait on the line. Our Outlook Calendar connector guide covers the calendar half of this pairing. The prep gets better the more you save in your contacts. A note that says met at the trade show, runs a bakery, wants wholesale pricing is worth more than a bare name and number. Save the note once, at the time you meet someone, and every future prep reads it back to you.

Build a list from the people you already know

Ask Muse to pull together the people in your contacts who match a description you give: everyone at a certain company, everyone you tagged as a client, everyone in a city you are visiting. This is the fastest honest way to build an outreach list, because every name on it is someone you already know and chose to save. It is also the use where a messy address book shows. If half your contacts have no company saved and no notes at all, Muse can only hand you names, and names without context are not a list you can act on. Fix the next contacts you save, with a company and one line of context, and the lists get useful within weeks. Never use this to build a list of strangers. The connector only sees the people you saved, and that limit is a feature: it keeps your outreach to real relationships instead of cold names. In a work setting, this also means respecting the list: colleagues and clients you saved for work are for work, not for a side project they never agreed to hear about.

Spot the gaps in your address book

Ask Muse to look through your contacts and tell you what is missing: people with no email address, clients with no phone number, contacts with no company saved. This is a tidy up job that takes ten minutes with Muse and would take an evening by hand. The point is not a perfect address book. The point is that the next time you need to reach someone urgently, the number is there. Run this once a month. Fix the ten contacts that matter most and leave the rest. An address book with 50 complete entries for the people you actually talk to beats 500 half empty entries every time. Work address books have one extra gap worth checking: people who left the company and whose addresses now bounce. Muse can show you the entries. Only you know who still works there.

Keep names straight across mail and calendar

When Outlook Mail and Outlook Calendar are connected alongside Contacts, Muse can join the three together: who someone is, what you last said to them, and when you next meet them. Ask Muse who you are meeting tomorrow and it can tell you not just the names on the invite but who those people are and what is open with each of them. The contacts piece is the one that turns a calendar block with a name on it into a meeting you are actually prepared for. This is the full Microsoft 365 pairing, and it is the reason to connect all three from the same Microsoft account instead of mixing accounts. Three connectors on one account agree with each other. Three connectors on three accounts argue.

5. What can it not do?

The limits are honest and worth knowing before you lean on the connector.

• It cannot find people you never saved. If someone is not in your Outlook Contacts, Muse cannot pull their details from nowhere. It will tell you they are not there, and that answer is the correct one.
• It cannot invent contact details. A guessed email address is worse than no email address, because it looks right and goes to the wrong person. If Muse says it does not know, believe it.
• It cannot fix a messy address book. Duplicates, old numbers, and contacts with no details in them stay messy until you fix them. Muse can show you the gaps, but the fixing is still yours.
• It cannot see contacts in other accounts. It reads the Microsoft account you signed in with, nothing more. Contacts in a personal Google account, a second Outlook account, or a company directory you never saved stay invisible unless you connect those too.
• It cannot tell you which duplicate is current. If you saved the same person three times with three different numbers, Muse can show you all three. Only you know which number still works.

6. What should you watch for?

As of October 25, 2026, Outlook Contacts is a quiet, settled connector: live since September 8, still listed in the October 15 check of 54 connectors in the web app, with no October change reported. There is no new feature to chase here, so the habits around it still matter. Check every lookup against your contacts for the first week, especially when two people share a first name. A wrong person acted on fast is worse than a slow lookup you verified.

Be careful with what you saved. Contact notes sometimes hold things you would not want repeated: a private detail about someone, a candid note from a first meeting, a reminder that was only ever meant for you. Muse reads what you saved, so treat notes as something Muse can quote back. Keep notes factual and professional, and move anything truly private out of your contacts entirely. Work address books carry one extra caution: your employer may have its own rules about AI tools reading contacts. If your work account needs an IT admin approval to connect, that approval is also your sign that the connection is allowed. Do not work around an admin block. Ask your IT team first.

Check your data controls. In Muse settings, open Data controls and look at the switch for helping improve the models. If you do not want your chats used for training, turn it off before you start asking Muse to read your contacts. That switch controls whether Meta may use your chats to train future models.

Finally, remember the account question when you plan. The connector sees one Microsoft account, the one you signed in with. If your personal contacts and your work contacts live in different Microsoft accounts, choose the account that matches the work you want Muse to help with, and keep the other one to yourself. That split is also good privacy hygiene. If you live in Google instead, the equivalent connector is Google Contacts, which does the same job for your Google address book, and our Google Contacts connector guide covers it. The two guides together show the overlap plainly: the habits transfer, the sign in and the address book do not.

Frequently asked questions

What does the Outlook Contacts connector do in Muse?

It lets Muse look up the people you saved in Outlook Contacts and use their details when you write, plan, or prep. Ask for a person by name and Muse returns the email address, phone number, company, and notes you saved for them.

Is Outlook Contacts live in Muse now?

Yes. It has been live since launch day, September 8, 2026, and it was still listed in the October 15 check of 54 connectors in the web app. No October change to how it works has been reported.

How is Outlook Contacts different from the Google Contacts connector?

They do the same job for different address books. Outlook Contacts connects your Microsoft address book, Google Contacts connects your Google address book. Pick the one where your contacts live, or connect both and say which one you mean.

Can Muse add new contacts to my address book?

Do not count on it. The connector is for looking up the people you already saved. Save new contacts in Outlook yourself, and Muse will see them there.

What happens if two contacts have the same first name?

Tell Muse to stop and ask you which one you mean. Never let it guess between two contacts, because a guessed contact is a message sent to the wrong person.

Can I use the Outlook Contacts connector outside the United States, Canada, and Japan?

Not yet. Muse itself has launched in the United States, Canada, and Japan only. Join the waitlist and we will send you a fresh code on launch day in your country.
