Connecting **Outlook / Microsoft 365** gives you **Two-way sync**: Relivo sends from your Outlook address, and email between you and your contacts appears on their timelines and in the **Inbox**. You sign in with Microsoft, so you don't need an app password.

1. **Open the Email settings**

    Go to **Settings** > **Email**.

2. **Choose Outlook / Microsoft 365**

    Under **Connect a mailbox**, click **Connect** next to **Outlook / Microsoft 365**.

3. **Sign in with Microsoft**

    Sign in with your Microsoft account, and allow Relivo to read and send email.

4. **Check the connection**

    You come back to **Settings** > **Email**, which shows your address under **Connected mailbox** with the **Two-way sync** badge.

## What happens next

- Emails you send from Relivo go from your Outlook address and appear in your Outlook **Sent Items** too.
- When a contact replies, the reply appears in the **Inbox** and on their timeline.
- Email you send to a contact from Outlook itself is logged as well.
- Relivo also brings in your recent email with people who are already contacts, so their timelines aren't empty on day one. This runs in the background and can take a while on a large mailbox.

Only messages that match a contact's email address are logged. The rest of your mailbox is never imported.
