Adding Sender Policy Framework (SPF) records for Work 365

Pre-requisites

Performing this configuration will require the following:

• Work 365 Administrator Role user
• Access to your DNS control panel with the ability to add/modify DNS records.

Time required

This configuration is expected to take approximately 10 minutes

Additional Notes

Adding an SPF record does not guarantee that the email will not be marked as spam; however, it does mark Work 365 / Sendgrid as the permitted sender for your domain.the 

Procedure

1. An SPF record is a TXT record added to your domain with the following format:
   
   _v=spf1 include:[permitted-sender-1] include:[permitted-sender-2] … include:[permitted-sender-3] ~all_
   
   
2. If your domain does not have an SPF record, create a new TXT record with the following value and a TTL of 3600 seconds
   
   _v=spf1 ip4:149.72.41.211 ~all_
   
   
3. If your domain already has an SPF record, you must modify that existing record by adding
   
   _ip4:149.72.41.211 before the ~all_
   
   
4. For example, if your domain already has an SPF record as follows
   
   _v=spf1 include:spf.protection.outlook.com include:servers.mcsv.net ~all_
   
   
5. The resulting record should look like
   
   _v=spf1 include:spf.protection.outlook.com include:servers.mcsv.net ip4:149.72.41.211 ~all_
   
   
6. Once the record has been added, it may take up to 72 hours to come into effect.

Congrats Your SPF record has been added!
