Hello,
I have installed two independent Exchange 2013 servers. They both run as virtual machine in Hyper-V. One has Server 2008 R2 and Exchange Server 2013 RTM and second has Server 2012 and Exchange Server 2013 CU1.
I made some basic settings - reconfigured Receive Connectors, created Send Connector, set internal and external addresses for virtual directories, change SSL certificate and installed and configured antispam agents - ./install-AntispamAgents.ps1
Both are experiencing same problem - I cannot send any e-mail, inside or outside organization, they all stay in Drafts folder, I tried it from OWA.
I have not tried it when it was clean installation.
Where could be a problem?
