What if you have domains added to your M365 tenant for account management purposes, but you use a different service to send email from those domains and therefore set up the MX and SPF records with values other than the protection.microsoft.com values Microsoft wants to see?
Those domains will be listed as misconfigured in the M365 portal.
Is there any fix for this?
