HI all
Today i just configured Office Web with Exchange 2013 SP1 and strictly followed the technet : http://technet.microsoft.com/en-us/library/jj150495(v=exchg.150).aspx
For information my Office Web App works fine with Lync 2013 on the same infrastructure
- I fixed the WACDiscoveryEndpoint with : https://officewebapp01.company.loc/hosting/discovery/
- I’ve recycled MSExchangeOWAAppPool 20 times !
- I can see in the event log the Event 142 in each CAS Server

But when I try to display a content …. White Windows… .pfouuuuuu L((((

And the worse is:: if you can’t see the preview you can’t download it !!!

Who is the silly guy who decided this behavior???? !!!!!!! : That’s nonsense!!!
Perform these cmdlets..
- Set-OwaVirtualDirectory « SRVEX1\owa (Default Web Site) » -WacViewingOnPrivateComputersEnabled $true
- Set-OwaVirtualDirectory « SRVEX2\owa (Default Web Site) » -WacViewingOnPrivateComputersEnabled $true
- Set-OwaVirtualDirectory « SRVEX1\owa (Default Web Site) » -WacViewingOnPublicComputersEnabled $true
- Set-OwaVirtualDirectory « SRVEX2\owa (Default Web Site) » -WacViewingOnPublicComputersEnabled $true
- set-OwaMailboxPolicy -identity default -ForceWebReadyDocumentViewingFirstOnPublicComputers $false
- set-OwaMailboxPolicy -identity default -ForceWebReadyDocumentViewingFirstOnPrivateComputers $false
- set-OwaMailboxPolicy -identity default -ForceWacViewingFirstOnPublicComputers $False
- set-OwaMailboxPolicy -identity default -ForceWacViewingFirstOnPrivateComputers $False
Better Behavior. The content of the attachment could not be displayed but you can download it now!

I ‘ve just performed a Get-officeWebappsMachine and the health Status is Unhealthy.

I’ve changed the Certificat name to add the Server FQDN restart the Office Web app service
And verify that

Restart the officeWebapp and the situation is better

But I’ve got still this

I decided to install this NET-WCF-HTTP-Activation45 and and Reboot
After a reboot lots of event are now present in the event viewer. And

And I’ve got this

Trying to remove the component NET-WCF-HTTP-Activation45 and restart the server

So beautiful !!! For a fresh installation !
And after 5 minutes……

And the result in OfficeWebapp is ….

Hopefully the farm is healthy!
Let’s recycling the OwappPool application on the exchange server … No 140 events!
Let’s verify if when I reboot the OfficeWebapp the officeWebApppsMachine is healthy. Surprise!!!!!!!!

But after 6 minutes the farm is healthy again.. coooollllll.

One Exchange server have the 142 event in the application log the second one no. I tried to use OfficeWebApp from the exchange server who have the 142 event. You know what???? The display content of the attachment is still a white page…!. Common!!! I’m starting to understand why you can freely download Officewebapp!
