New exchange server - When I am trying to send email from my local network or outside the network to gmail or hotmail, I am getting Delivery Failed message immediately to my inbox
----> from ******@anotherdomain.com to outside@Luxsparks .com & outside@Stuff .com

-> mail.mydomain.com.uk is mail domain,
-> anotherdomain.com is accepted domain for send and receive email

following is the error

    Hi,

    You mean you have created receive and send connectors to route though the edge server?

    It is not necessary, as edge subscription would automatically create the connectors for you.
    I suppose it could cause some problems.
    I would recommend that you could disable the connectors that you have created by yourself and see if that changes.
