Hello Everyone,

I updated for 2013 CU 2 to CU 13. The update completed successfully but when I tried logging onto the ecp I got the error below.

I have tried going to C:\Program Files\Microsoft\Exchange Server\V15\ClientAccess\ecp and all files are still there

Tried reattaching ecp file through IIS

Tried recreating ECP with no luck.

Ran the following through powershell:

Set-EcpVirtualDirectory -Identity "mail.local\ecp (Exchange Back End)" -WindowsAuthentication $true -FormsAuthentication $false


New-EcpVirtualDirectory -Server JBIMAIL -WebSiteNameExchange Back End -ExternalURL https://mail.secrets.com/ecp -InternalURL https://mail.secret.com/ecp

Remove the Site in Default Web Site
 Remove-EcpVirtualDirectory -Identity "ecp (Default Web Site)"

 Remove the Site in Back End
 Remove-EcpVirtualDirectory -Identity "ecp (Exchange Back End)"

 Recreate the Site in Default Web Site
 New-EcpVirtualDirectory -WebSiteName "Default Web Site"

 Recreate the Site in Back End
 New-EcpVirtualDirectory -WebSiteName "Exchange Back End"

I have tried everything under the SUN with no luck. If there is a possible solution that we can find. Please let us know.

Server Error in '/ecp' Application.
