Hello

Yesterday I have test lab with Exchange Server 2013 Sp1 for site resilience.

For information i have two data center include:

Primary site :

1 AD DS

1 Client Access Server

1 Mailbox Server role

Secondary site :

1 AD DS

1 Client Access Server

1 Mailbox Server role

Issue happen when test case.

When me shutdown only mailbox server in primary site. A mailbox have availability can send and receive from External e-mail but when me send message from external mail to Distribute group recipient not receive mail. The external mail status retry...

But when start Mailbox Server the recipient in distribute group can receive message from external e-mail.

Who have issue such  ?

Thank you.
