I need some help wrapping my mind around 'SPF' records for Office 365. We don't have any 'on premise' email servers, we use Office 365.
This is the record showing under domains in Office 365: 'v=spf1 include:spf.protection.outlook.com -all'.
I also have an SPF record at our DNS host('v=spf1 include:outlook.com ip4:18.104.22.168 ~all') that includes our network's external IP address. Is this still necessary if we don't have any local email servers and should I replace it with the SPF record showing in Office 365?
Thank you for your help!
