Hello all,

I have Edge transport server 2013

Also there are 3 Exchange servers installed

Ex01(Exchange 2010)

Ex02(Exchange 2013)

Ex03(Exchange 2013)

In the near future I will migrate all Databases from Ex01(Exchange 2010) and dismout the server and there will be Ex02(Exchange 2013) and Ex03(Exchange 2013) servers only

For now everything is working well, incoming/outgoing e-mails etc. but when I disable Ex01(Exchange 2010) I cannot send any external e-mails from mailboxes which located in Exchange 2013 servers(no problems with receiving e-mails appear)

When look in the queue of Exchange 2013 servers I can see all e-mails which got stuck in the queue.

What might that be? Please, help to resolve the issue.

Do you have a send connector for ex02 and ex03 where they can go out to the internet?  Is the edge server configured to accept mail from ex02 and ex03?

Hi,

As Hinte mentioned, it seems that you have a send connector configured for Outbounding on Ex01 only. If you disable Ex01, Outbound should be disabled.

Please check whether you have other send connectors configured on Ex02 and Ex03 for Outbounding.
