Hi there,
I've been dealing with some bounces from domains that are hosted on Office365 (not independently) but from additional services purchased by GoDaddy, Register.com, etc.
I've been dealing with some bounces from domains that are hosted on Office365 (not independently) but from additional services purchased by GoDaddy, Register.com, etc.
The bounce error is "[name] wasn't found at domain.com" with a Status code: 550 5.1.10 - https://docs.microsoft.com/en-us/Exchange/mail-flow-best-practices/non-delivery-reports-in-exchange-online/fix-error-code-550-5-1-10-in-exchange-online
Also, those email addresses are all verified (tried with multiple services), so it's not a case of an invalid email address. As I've previously mentioned, all these domains that are bouncing like this "most probably" got Office365 plan from their registrars, hosting providers, etc. (I've done MX / NS Lookups to verify this) -
So, have you also experienced this kind of issue before?
