I have setup Exchange 2013 SP1 on Server 2012R2 from scratch. I have added AD users and setup all the mailboxes for them.
However, when I try to send email from OWA to internal mail accounts, other users cannot receive and mail at all.
I have tried to send a email to my own account and I still cannot receive anything.
There is no other setting I have done at all.
Please let me know what information I need to provide to solve the issue.
