Hi, 

I am not able to access the ECP website or OWA. I first started to get error "Something went wrong", but now for some reason when I go to the ECP page it says:

"Access denied" -

You don't have permission to open this page. If you're a new user or were recently assigned credentials, please wait 15 minutes and try again.

I am sure this has to be with IIS permissions, but I don't know how to fix it. Please help 

And when i go to the OWA site it says:

"Invalid credentials"
