Configure Microsoft

Please note that this is a legacy setup for email relay and the information on this page may be out of date including the IP addresses.

We recommend using the Microsoft recommended Authenticated email option: SMTP Authenticated Emailing - Knowledge Base - Campus Cafe (atlassian.net)

Configure Campus Cafe

The MX record for the domain and port to connect on will be needed. To find your MX record ask your system administrator or use a tool such as MX Toolbox.

  1. Navigate to Admin > Web App Config

  2. Locate the Parameter SMTP_HOST and, for the value, enter azure_ followed by your MX record. This will look something like azure_yourschooldomain-com.mail.protection.outlook.com

  3. Locate the Parameter SMTP_PORT and, for the value, enter 25

  4. Refresh the Data Cache (Admin Menu → Refresh Data Cache)

Configure Microsoft 365

Update SPF Records

Typically, this record must be updated in the system of the vendor that manages your institution's domain. 

To determine where your SPF records are managed:

  1. Log in to the Microsoft 365 Admin Center (if you are currently in the Exchange admin center, return to the main Microsoft 365 Admin Center)

  2. In the left-hand menu click Settings > Domains

  3. Click the link to the domain associated with the email addresses that will be relayed

  4. Select DNS records on the next page

  5. At the top of the screen if the following message: "To manage DNS records for yourdomain, go to your vendor" appears at the top, stop and proceed to make the changes with the DNS vendor.  Otherwise, proceed to step 6.

  6. Update the SPF record value to include "v=spf1 IP4:3.132.35.147" and "v=spf1 IP4:3.18.151.171"
