# SMTP Device Inventory Manager sends emails to your people: expiry alerts, scheduled exports, new users to approve, onboarding and offboarding confirmations for employees. These emails leave from **your** mail server, so that they come from a sender your users know and trust. Configure it in **My Tenant** › **Edit** › **SMTP**.  | Field | Value | | --- | --- | | **SMTP Server** | The address of your mail server or relay, for example `smtp.office365.com`. | | **Port** | Usually `587`. | | **SSL/TLS** | **Enabled** for port 587 or 465. | | **Email language** | The language of the emails sent to employees and users: Italian or English. | | **Username** / **Password** | The account used to authenticate on the server. Leave the password empty to keep the one already saved. | | **From email** / **From name** | The sender shown to recipients, for example `it@contoso.com` and *Contoso IT*. | Click **Save**, then check the configuration: enter your address in **Recipient email address** and click **Test send**. If the test email does not arrive, check the server, port, credentials and that the account is allowed to send as the **From email** address. > With Microsoft 365, the account must be allowed to use authenticated SMTP (SMTP AUTH). Alternatively, use an SMTP relay or a service such as Azure Communication Services. ## What depends on SMTP | Email | Without SMTP | | --- | --- | | [Email Notifications](https://wiki.cyberguard.srl/dim/administration/email-notifications.md): expiries, scheduled exports, networks almost full, new users to approve | Not sent. The **Notifications** tab asks you to configure SMTP first. | | [Staff Management](https://wiki.cyberguard.srl/dim/staff-management.md): onboarding confirmations and offboarding reports for employees | Not sent. | If the password of the mail account changes or the account is disabled, emails fail without further warning. Update this tab whenever you change the account.
