# Set up Office 365 as mail server in OpManager

OpManager allows you to configure Office 365 as the SMTP server to send alert notifications, scheduled reports and more.

**Important Note:** Prior to mail server configuration, go through [this mandatory check list](https://www.manageengine.com/network-monitoring/kb/Mail-Server-troubleshooting.html) to avoid connection issues.

To set it up as your mail server, follow the simple steps below.

1. Go to **Settings** tab.  
2. Select **Basic Settings → Mail server settings** in the left pane.  
3. It is recommended to use the Office 365 SMTP server settings and not use IMAP or POP configurations.  
4. Enter **smtp.office365.com** as the Server Name and the Port number as **587**. Enter **Timeout** in the range of **1–300 (sec)**.  
5. In the **From Email ID field**, enter the Office 365 address from which the mail should be sent.  
6. In the **To Email ID field**, enter the receiver's email address. If you want to enter multiple email addresses, separate them using a comma.  
7. In Authentication Details, provide the **Office 365 credentials**, i.e., the User Name and Password for the Office 365 account mentioned in the From Email ID field.  
8. Select **TLS** in Secure Connection Details.  
9. Send Test Mail to check the configuration.  
10. Click **Save**.

**Note:** The Office 365 account you are configuring must have a mailbox.
