In the last part of this Exchange 2016 migration series we looked at installing the first Exchange 2016 Mailbox server into the Not Real University organization. Now it’s time to configure the client access services for the new server.
Not Real University is using the same client access namespaces for Exchange 2016 as the existing Exchange 2010 and 2013 servers, so there are already DNS records in place. If you are deploying Exchange 2016 into a different site with new namespaces, you should add the DNS records for the namespaces first.
The Exchange 2016 client access namespace configuration can be performed using the Exchange Admin Center, but that’s the slow way of doing it. Instead, let’s use a PowerShell script that is built for this purpose, called ConfigureExchangeURLs.ps1. You can download it from the TechNet Gallery.
To configure the Not Real University Exchange 2016 server, the command is:
PS C:Scripts> .ConfigureExchangeURLs.ps1 -Server NREXCH16 -InternalURL mail.notrealuniversity.com -ExternalURL mail.notrealuniversity.com -AutodiscoverSCP autodiscover.notrealuniversity.com
Next, the SSL certificate needs to be configured. If you’re new to the topic of SSL for Exchange, you can learn more about it here. Not Real University is using the same certificate that is already in use on the Exchange 2013 and 2010 servers, so the steps are:
- Export/import the SSL certificate to the new server
- Enable the SSL certificate for services in Exchange Server 2016
For environments where a new certificate is required, the steps are:
- Generate a certificate signing request (CSR) for Exchange Server 2016
- Submit the CSR to your chosen certificate authority
- Complete the pending certificate request on the Exchange server
- Export/import the SSL certificate to any additional servers (for multi-server scenarios)
- Enable the SSL certificate for services in Exchange Server 2016
After the SSL certificate has been installed and enabled, restart IIS on the server for all of the recent changes to take effect.
In the next part of this series, we’ll look at configuring mailbox databases.

Hi Paul,
Sorry to have bothered you, I found out what the problem was and fix it. I did not changed the forwarding on my router. After i did that everything works. i am now n=monitoring my mails for a couple of days before I decommission the old server.
Thank you for the excellent guide

Hi,
We migrated from Exchange 2010 to Exchange 2016, and I’m trying to decommission the 2010, I dismounted the Database for the 2010 and everything is working perfect, we can send and receive Email from in and outside the school.
but when I try to shut down the 2010, I no longer can receive Emails, but I can send, is it related to Hub Transport under Server Configuration in the 2010?.
I’ve been reading for over couple of weeks and following the steps to make sure everything was done right in the migration, but I still can’t find what I have missed to decommission.
I appreciate any help & advice.
Sorry, one correction .
Hi Paul,
I’m facing a big problem with my Exchange migration from 2010 to 2016.
My Exchange 2010 environment has 2 Exchange Servers (installed on Windows Server2008 R2) and 2 DB Servers with CAS Array and DAG. One exchange Server and DB Server is hosted on one Datacenter and the others on another datacenter.
Ex10srv1, Ex10mdb1 — on datacenter 1
Ex10srv2, Ex10mdb2 — on datacenter 2
CAS (Ex10srv1, Ex10srv2)
I installed 2 new Exchange 2016 Servers (Ex16db1, Ex16db2).
Ex16db1 — on datacenter 1
Ex16db2 — on datacenter 2
I migrate one test mailbox from Exchange 2010 to Exchange 2016 but i can open it with Outlook 2010.
Please assist me with this migration.
Thanks in advance

Paul, how about the preferred authentication settings on the VDs? Currently I am using Exchange 2010 with ADFS (Server 2012 R2).
Thanks.

Hi.
Don’t you have any consideration on migrating POP/IMAP from 2010 to 2016?
Is enabling and apply same configuration on new servers, enough?
Should the service be configure and enable on all new servers?

Yes, just make sure the servers are started and the config is the same, and then update the pop/imap DNS records to cutover clients. It’s pretty straightforward for pop/imap.
Hey Paul
Even looking after info requested by earlier gents above.

Hi Paul,
I follow you on Twitter (great stuff btw), and use this site pretty religiously for all things Exchange in my lab. I’m eager to see the tutorial the gentleman previously has asked about as well.
I’m currently working on upgrading from 2010 (build 14.3.123.4) to 2016 for a customer of mine.
As always, thank you for the great stuff you put on here and Twitter.

Hi Paul
Great series of tutorials.
Do you have any tutorials on cutting over client access services from Exchange 2010 to Exchange 2016?
