The Exchange admin center (EAC) is the modern-day web-based management console for managing recent versions of the Exchange Server. It replaces the Exchange Control Panel (ECP) that allows you to control your mail settings. There are times when you try to launch EAC, and you’re stopped by a message saying, “Could not load file or assembly.”
This means you ‘cannot access ECP on new Exchange 2019 server,’ and further communication won’t be possible.
There are instances when you migrate or update the previous version of your Exchange Server to the recent one. One of such errors we found while running EAC after the update is mentioned here:
Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately.

Approaches to fix “Cannot access ECP on new Exchange 2019 Server”
When you find an issue like this, there is never a single cause behind it. You need to check multiple ways to find out what the actual issue is and then respectively find a suitable solution. Hence, to resolve the error, we’ll need to verify multiple conditions.
Is OWA working fine?
Outlook Web Access, or Outlook on the Web, is a web-based email client that allows users to send and receive email messages just like MS Outlook. Before you proceed to find a solution to fix the error, validate if OWA in your MS Office 365 is working.
Sometimes, OWA and EAC become inaccessible after a Cumulative Update (CU) or migration to an updated version. However, if OWA is working completely fine, there is a problem with the EAC mainly.
Did you try with other browsers and accounts?
Try accessing the Exchange admin center with other admin accounts, different web browsers, and local servers in your organization. It will provide a clear picture of the issue, showing if the error is in one single account or the EAC of your Office 365 account.
Check EcpVirtualDirectory
The ECP Virtual Directory works for the on-premises Exchange. Use the command “Get-EcpVirtualDirectory” to view the ECP Virtual Directory used in the Internet Information Services of Microsoft Exchange.
The Exchange Control Panel Virtual Directory is used in EAC. The EAC virtual directories and the connected cmdlets in Exchange Server 2013 and Exchange Server 2016 still have ECP in the name. You can use the cmdlets for ECP virtual directory management on Exchange 2010, 2013, and 2016 servers.
Run the following syntax in the Power management shell:
The command won’t provide output if you do not have the required permissions assigned to your account, so make sure to have them before running it.
Did you migrate from Exchange 2013 to Exchange 2019?
Sometimes, when you migrate from Exchange 2013 to Exchange 2019, the arbitration mailboxes remain untouched. This can become a hurdle to access the admin center in the updated Exchange.
Arbitration mailboxes are the system mailboxes that require migration before moving to the recent version of the Exchange server. These mailboxes store organizational data, such as audit logs and unified messaging data. Move your arbitration mailbox to Exchange 2019 or create a local mailbox on Exchange 2019 and make it the organization admin.
