Step 1: Create One TXT Record

Important that you create only one TXT record for SPF.

Step 2: Append The New Office 365 Values

If you already have an SPF record, then you should append the new office 365 values to do it, instead of creating a new one.

Step 3: Ensure The Syntax Is Correct

After you update the SPF record, you should check to make sure that the syntax is correct by using the tools:

    • SPF Record Tools
    • SPF Surveyor
    • Dig Web Interface
