I have setup all the proper configuration but am having a problem with the email address.
I receive email if I am using @mydomain.onmicrosoft.com but will not receive any mail if it just addressed to @mydomain.com
When I send an email, the email address sent from is just @mydomain.com and is received by the recipient yet if the recipient replies to that address it is not received by me.
If they add the onmicrosoft.com to the address it is received.
Any help would be greatly appreciated.
