#### 5. Done!
You'll see "Connected to Microsoft" and a verified mailbox.

### Managing the integration
To disconnect: **4 dots -> Account -> Integrations and add-ons** -> **Microsoft SMTP** -> **Launch** -> **Disconnect**.

### Common issues
- **"Organization doesn't allow this application"** - IT admin must approve in Entra ID
- **"Invalid scope"** - log out of Microsoft and retry
- **403 error** - ensure you're logged in as Sugester administrator
- **Mailbox didn't appear** - check you logged into the correct Microsoft account

### Data security
Sugester **does not store your password**. You can revoke the token at [https://account.live.com/consent/Manage](https://account.live.com/consent/Manage).
