Hi @Jeff Gray ,

I just got an email bounced saying that I needed to set up SPF or DKIM on my email account. I have a custom domain, hosted free by Microsoft.

If by "custom domain", you meant the initial 'onmicrosoft.com' domain, both SPF and DKIM should have already been automatically setup so normally you don't need to do anything else manually. If this is your scenario and the bounce back mail still comes in, kindly remove all private information like real email address or domain name and then share a sample of the error details so that we can help look into it.

If you are referring to your own custom domain, you can refer to the instructions in the following links to set up the SPF and DKIM:

• Set up SPF to help prevent spoofing
• Use DKIM to validate outbound email sent from your custom domain
