IT Solution

This is down to the security on the OWA virtual directory and the ECP not matching, the quickes way to fix this is to regenerate both virtual directories. Use the commands below to do so.

Open the exchange managment shell and enter the below.

Remove-OwaVirtualDirectory -Identity "owa (default Web site)"

Then

Remove-ECPVirtualDirectory -Identity "ecp (default Web site)"

Then

New-OwaVirtualDirectory

Then

New-ECPVirtualDirectory


then

Reset IIS.

This will have recreated both OWA and ECP virtual directories, you will be able to login to the ECP now.

    Also possible that you disabled the forms based authentication on the owa directory and didn’t disable it on the ecp directory…
