# Microsoft Exchange

> Send Wave emails from your Exchange mailbox over SMTP

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

Connect a Microsoft Exchange or Outlook mailbox to Wave for outbound email sending via SMTP with OAuth2 authentication. This suits organizations running Microsoft Exchange Server or Microsoft 365 with Exchange Online.

## How to Connect

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

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

  <Step title="Set a custom sender (optional)">
    Enter a custom **sender email address** if you want Wave to send from a different address than your logged-in account.
  </Step>
</Steps>

Your email address and display name are detected automatically unless you specify a custom sender. Wave requests offline access (to keep the connection active) and permission to send email via SMTP on your behalf.

## What Gets Synced

This integration is for sending only.

**Direction**: Outbound only (Wave → Exchange SMTP → recipient)

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

## Features

* Emails sent by Wave come from your Exchange mailbox address.
* Uses OAuth2 for SMTP authentication (not basic auth), in line with Microsoft's modern auth requirements.
* Supports custom sender addresses for shared mailbox scenarios.

## Limitations & Requirements

* **SMTP AUTH must be enabled** on your mailbox in the Microsoft 365 Admin Center. If it is disabled (the default for some tenants), Wave cannot send emails. Contact your IT administrator if you are unsure.
* The connection uses STARTTLS on port 587 (`smtp.office365.com`).
* This is a personal integration, connected per user.

## Disconnecting

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