Fix
===
$e = Get-SPServiceApplication | where {$_.TypeName.Equals("Word Viewing Service Application")}
$e.WordServerIsSandboxed = $false
$e.WordServerIsSandboxed
Browsed to server’s “c:windowssystem32inetsrvconfigapplicationHost.config” and added the following line below in the end of the dynamicTypes.
note we are using the value TypeName not the name of the Service Application – this doesn’t need changing
$OffWASvcPoolIdentity="DOMAINWordAP";
Get-SPWebApplication|%{ $_.GrantAccessToProcessIdentity($OffWASvcPoolIdentity);}
