I have an Ex2k13 setup as :
Win2012 R2 DC
Win2012 R2 + Ex2k13 act as CAS and MBX server
now i promoted a new Ex2k13 node to configure DAG between them , but once the installation of the new exchange finished and before doing any settings related to DAG or any send/rcv connector , i started receiving complains about some internal users can't send/rcv internally although the mailbox is connected ,
at first i checked queue and i found many emails in the shadow queue , although it shudn't be related to the problem but i disabled it then i had to stop all transport services and other exchange services in the new Exchange node and then the users started to send / rcv normally !
what cud be the reason ? and how to avoid it ?
