Exchange 2010 ECP / OWA see all options button, 500 Internal Server Error

Had an issue today where the Exchange OWA, “See All Options” button didn’t work.

When you click this button it actually tries to redirect you to https://servername/ecp. This then causes the error :

500 - Internal server error. There is a problem with the resource you are looking for, and it cannot be displayed.
server500

To resolve the issue I recreated the ecp virtual directory.

First of all you have to remove it.

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

Press Y to confirm removal.

Then to put it back do the following :

New-EcpVirtualDirectory -externalurl "https://externalurl/ecp" -internalurl "https://internalurl/ecp" -Server "servername.fqdn"

Do an IISRESET and you should all be good. The error went for me.
