I am experiencing difficulties with my send and receive connectors in Exchange 2013.
We have had big issues with our Exchange, but I managed to reinstall Exchange 2013 (CU1) and recover the database.
Now, I have the problem that:
- Outlook (client) can not connect to the server.
- I can not send messages OUT (using OWA)
- I can not receive messages. Telnet to external interface port 25 returns "421 4.3.2 Service not available". (Yes, anonymous authenticaction is ON and binding on IP 0.0.0.0/255.255.255.0)
Also, NO Anti-Virus is running, Mailware checking has been disabled and when I telnet to the WAN interface ON THE SAME MACHINE, I *DO* get a telnet port 25 reply...
I have tried everything. Link DNS servers to outgoing interface, reset Certificates, recreate connectors. No Luck.
I am thinking my send and receive connectors are somehow damages. Is there a way I can delete them and let exchange recreate the default ones using some sort of powershell script?
What can we do here?
Can anyone help?
