Exchange 2016 ECP redirects to Exchange 2010 ECP
Log in to the Exchange Server 2016 and start a web browser. Before you start, I recommend deleting the cache of your browser. Go to the URL https://localhost/ecp. If you get a warning of the certificate, proceed further.
Log in with your administrator credentials.
Exchange 2010 ECP is showing after entering the credentials.
Why are we getting redirected to ECP 2010, and what is the solution for Exchange 2016 ECP redirect to Exchange 2010 ECP?
Fix for Exchange 2016 ECP redirects to Exchange 2010 ECP
First, find the Exchange version with PowerShell. After that, add a question mark and the Exchange Client version after the URL https://localhost/ecp. It will look like the following:
- Exchange Server 2016: https://localhost/ecp?ExchClientVer=15.1
- Exchange Server 2013: https://localhost/ecp?ExchClientVer=15.0
We are running Exchange Server 2016, and that’s why we are going to use https://localhost/ecp?ExchClientVer=15.1. Copy and paste the URL in the browser. Exchange Server 2016 ECP is showing, great!
From now on, you can use that URL in your browser to reach Exchange Server 2016 ECP. Do you want to get back to Exchange 2010 ECP? Remove the extra string that you added.
Solution for Exchange 2016 ECP redirects to Exchange 2010 ECP
The Exchange 2016 ECP redirect to Exchange 2010 ECP is happening because the administrator mailbox is on an Exchange 2010 mailbox database. If you move the mailbox to the Exchange 2016 mailbox database, this will not occur. You will be able to directly login to Exchange 2016 ECP with the URL https://localhost/ecp.

I encountered the same issue.
Using (Network Console> developer mode of IE) What I noticed was when you browse server 1, it will load IIS application of Exch server 2. So if you localhost/ecp in server, it loads IIS Exch backend of server 2. We resolved the issue by creating DNS entry for new server and use that DNS to access ECP instead of directly connecting to its hostname.
Thank you for the guide.
actually I am facing same issue but the administrator has no mailbox but still its going to 2010 owa,
any idea?
What about the account that you are logging in with? Move that mailbox to the new mailbox database.
Did you try to log in with a private browser window?
If the above is not working, create a new admin AD account with a mailbox in the newly created mailbox database. Log in with that account.
