# Office 365

> Send Wave emails via the Microsoft Graph API

<Info>
  Available on the **Enterprise** plan.
</Info>

Connect a Microsoft 365 account to Wave for outbound email sending via the Microsoft Graph API. Unlike the Exchange SMTP integration, this uses the Graph API's `Mail.Send` endpoint, so no SMTP AUTH configuration is required.

## How to Connect

<Steps>
  <Step title="Open the integration">
    Go to **Integrations → Office 365**.
  </Step>

  <Step title="Connect Microsoft 365">
    Click **Connect** and sign in with your Microsoft 365 account.
  </Step>

  <Step title="Set a shared mailbox (optional)">
    Enter a **Send from** email address if you want to send from a shared mailbox.
  </Step>
</Steps>

Wave requests offline access (to keep the connection active) and permission to send mail. The shared-mailbox permission is requested only if you provide a shared mailbox address.

## What Gets Synced

This integration is for sending only.

**Direction**: Outbound only (Wave → Microsoft Graph API → recipient)

**When**: Per email send (no background sync)

## Features

* Emails sent by Wave come from your Microsoft 365 address.
* Supports shared mailboxes by specifying a custom sender address.
* Uses the Microsoft Graph API, so SMTP AUTH does not need to be enabled on your tenant.

## Limitations & Requirements

* To send from a shared mailbox, your account must have **Send As** or **Send on Behalf of** permission on that mailbox.
* This is a personal integration, connected per user.

## Disconnecting

Go to **Integrations → Office 365** and click **Disconnect**. This removes the integration. Future Wave emails revert to the default Wave sender address.
