Available on the Enterprise plan.
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

1

Open the integration

Go to Integrations → Office 365.
2

Connect Microsoft 365

Click Connect and sign in with your Microsoft 365 account.
3

Set a shared mailbox (optional)

Enter a Send from email address if you want to send from a shared mailbox.
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.
