Powershell and EAC still connects to old servers after migration

I just mygrated from Exchange 2013 to Exchange 2019 and everything went well. But one thing starts to annoy me. When I use EMS and/or EAC it still connects to the Exchange 2013 environment and the server on which my admin account "lived" before the migration.

I tried to logout and restart the computer from which I run the EMS from, I deleted the C:\Users\username\AppData\Roaming\Microsoft\Exchange\RemotePowerShell folder. I searched through the registry. Restarted the two powershell application pools on the old Exchange 2013 server etc...But no luck.

Anyone got Ideas?

Regards

Michael

    What does the connection string look like that you are using to connect? Did you update to point to the 2019 servers?

    I assume you moved all the arbitration mailboxes to 2019 as well.

    Hi, Michael.

    To change the server EMS connects to, please follow these steps:

    1. locate the path of EMS, by default it should be like C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Microsoft Exchange Server 2019
    2. right click on "Exchange Management Shell" and select "Properties"
    3. in "Target", change the "Connect-ExchangeServer -auto" part to "Connect-ExchangeServer <FQDN of Exchange 2019 server>"

    Launch EMS and check if it connects to the Exchange 2019 server instead of the Exchange 2013 server.
