So your Office Web Apps isn’t working….Suddenly stopped working

Written by Peter Ward on October 8, 2016 – 12:28 pm -

This happened to me the other day.

So how to troubleshoot… Look in the ULS logs.

To configure office web apps you’ll need:

-Office Web Apps Farm Internal URL:
-Office Web Apps Farm External URL

For me it turned out to be the certificate.

I found errors in Office Web Apps ULS logs, so I had also run Get-OfficeWebAppsFarm command which showed me the same error that the computer is not part of an Office Web Apps Server Farm. So I tried creating new farm using New-OfficeWebAppsFarm comment yesterday where I used “*” as certificate name in this command, but I got error that certificate was not found. Then today I used the friendly name of certificate and it worked.

New-OfficeWebAppsFarm -InternalUrl “” -ExternalUrl “” -CertificateName ” domainnameDigiCert Wildcard” -EditingEnabled

This problem usually happens due to windows updates getting installed on Office web apps server.
