I'm seeing an error when trying to delete a message through OWA.
"The action you tried to perform couldn't be completed because there's a configuration problem on the server. If the problem continues, contact your helpdesk. The entire error report is listed below..." (listed below is the same text as shown here)
The problem appears when we try delete email in OWA from outside.
Light version and internally it works fine.
No host in bindings
Also there is event ID 108
