"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

- Go to C:\Windows\System32\Inetsrv and execute below command:
add backup "BackupToday"

- Please Run the "UpdateCAS.ps1" powershell script from the Exchange install directory scripts subfolder. The command example is as follows:
C:\Program Files\Microsoft\Exchange Server\V15\Bin>.\UpdateCas.ps1

After that post the output and try to access owa and let me know.

The version number indicates that you are on SP1 (aka CU4). That means your server is very out of date (SP1 was released in Feb 2014). We are on CU8, about to be CU9 (if MS is on schedule) very shortly.
I would suggest updating the server to CU8, and see if that resolves the problem.
