anyone ever have some problem with me?. pls help

Hi,

From your description, I recommend you follow the steps below to verify if the "Anonymous users" is checked.

Open EMC -> Server Configuration -> Hub Transport -> Default receive connectors -> right click -> Properties -> Permission groups -> Anonymous users

Hope this can be helpful to you.

Best regards,

Hi Amy Wang,

i have done this action, to give permission for anonymous user, but its not works.still receive bouncing if i receive message from external.

actually default receive connector should be route message to mailbox in different site, right?
