Office 365 mail server configuration

Office 365 is a cloud-based email service provided by Microsoft, and configuring the mail server settings is a bit different from traditional on-premises email servers. Here's a step-by-step guide to help you configure your Office 365 mail server settings:

Step 1: Set up your Office 365 account

  1. Go to the Office 365 admin center (https://admin.microsoft.com) and sign in with your admin credentials.
  2. Click on "Users" and then "Active users" to view the list of users in your organization.
  3. Click on the user you want to configure the mail server settings for.

Step 2: Enable mail flow

  1. In the user's profile, click on "Mail" and then "Mail flow" to enable mail flow for the user.
  2. Make sure the "Mail flow" toggle switch is turned on.

Step 3: Configure mail server settings

  1. In the user's profile, click on "Mail" and then "Mail server settings" to configure the mail server settings.
  2. In the "Mail server settings" page, you'll see the following settings:
    • Incoming mail server: This is the server that receives incoming emails. The default value is smtp.office365.com.
    • Outgoing mail server: This is the server that sends outgoing emails. The default value is smtp.office365.com.
    • Port: The default port for incoming and outgoing emails is 587.
    • Authentication: You can choose to use either "Basic" or "OAuth" authentication.
  3. Click "Save" to save the changes.

Step 4: Configure your email client

  1. Open your email client (e.g., Outlook, Thunderbird, etc.) and go to the settings or preferences.
  2. Look for the "Account" or "Email" settings and click on it.
  3. Enter the following settings:
    • Incoming mail server: smtp.office365.com
    • Outgoing mail server: smtp.office365.com
    • Port: 587
    • Username: Your Office 365 username (e.g., [your email address])
    • Password: Your Office 365 password
  4. Click "Save" to save the changes.

Additional settings

  1. SPF (Sender Policy Framework) record: You may need to set up an SPF record to prevent spam emails. You can do this by going to the Office 365 admin center, clicking on "Settings" and then "Domain" and then "TXT records".
  2. DKIM (DomainKeys Identified Mail) record: You may need to set up a DKIM record to authenticate your emails. You can do this by going to the Office 365 admin center, clicking on "Settings" and then "Domain" and then "TXT records".
  3. TLS (Transport Layer Security) settings: You may need to configure TLS settings for your email client or server. You can do this by going to the Office 365 admin center, clicking on "Settings" and then "Mail" and then "TLS settings".

That's it! With these steps, you should be able to configure your Office 365 mail server settings and start sending and receiving emails using your Office 365 account.
