Hi Aaron Yuan ,
The problem is the same , did I really must change my Name Server 1 and Name Server 2 to point to microsoft online server?There is another people doing testing also with E3 plan in my organization , using domain that my organization bought from the same domain registrar with me , but she not face any problem like this.So that why I need to know , why my domain need to change Name server, while her not.
Until now,
I successfully set this domain( peroneus.com) to be able to
1.send and receive email from internal organization.
2. successfully send email to outside ,but failed to receive any email from outside of the organization.
could you clarify what is happen?
