Good morning.
Form Exchange 2013 installation (fresh installation on a new server; old Exchange 2010 server dismiss and AD cleaned) I found some GREAT problems in sending mails: when clients send internal mails (but sometimes external mails also), MS Outlook (both 2013 and 2010) report "sending" but non mail came to recipient. In Tracking Log (Exchange console) there is no track of the mail. It seems to miss form Outlook to Exchange... As said, this happen for internal mails principally, but sometimes for extenal send also... I configured Exchange to use smarthost to send mails, and Hub Transport for receive connector. CU1 installed.
What can I try???
Thanks...
Luca
