# Connect Microsoft 365

Connect an Outlook or Microsoft 365 mailbox, with Microsoft sign-in or SMTP.

[Open in the app →](https://app.example.com/#/mailboxes)

There are two ways to connect a Microsoft 365 mailbox.

## Option 1: Sign in with Microsoft (recommended)

1.  Go to **Mailboxes** and click **Connect mailbox**.
2.  Choose **Microsoft 365**, then **Sign in with Microsoft**.
3.  Sign in and accept.

No password is stored. If this option says it isn’t set up yet, use option 2.

## Option 2: SMTP and IMAP

1.  Choose **Microsoft 365**, then the SMTP and IMAP option.
2.  Enter your full email address and password (or an app password, if your account uses one).
3.  Click **Connect**.

We sign in to check the details and send a test email.

## If the login fails

Many Microsoft 365 accounts have **Authenticated SMTP** turned off. Ask your admin to turn it on for this mailbox. They can do this in the Microsoft 365 admin center: open the user, then **Mail**, then **Manage email apps**, and tick **Authenticated SMTP**.

## After you connect

-   Fix any red SPF, DKIM or DMARC badges. See [Set up SPF, DKIM and DMARC](/help/dns-records).
-   New mailboxes start slowly. See [Sending limits and the slow start](/help/slow-start).
-   If Microsoft asks us to slow down, we pause the mailbox for 24 hours. It starts again on its own.
