Office Web Apps Server Antivirus Exclusions

Hello,
Are there any guidelines for Antivirus exclusions with respect to Office Web Apps server like we have for Exchange, Lync and SharePoint servers. I would highly appreciate if any help in this regard.
We have office web apps server that we are using with Lync 2013 and SharePoint 2013.
Thanks

Hi,
There is no Official documentation about it.
For servers running antivirus software, include all servers running Lync Server 2013 in the exception list in order to provide optimal performance and audio quality.
You may refer to the link below:

Using Office Web Apps Server with SharePoint Foundation 2013

I want to know whether I can configure Office Web Apps server to edit Excel documents on a SharePoint Foundation 2013 site.
I came across a TechNet article that states that "When used together with SharePoint Server 2013, Office Web Apps Server provides updated versions of Word Web App, Excel Web App, PowerPoint Web App, and OneNote Web App".
However, later in the same article, it states "If your organization licenses Office 2013 through a Volume Licensing program, you can enable Office Web Apps editing for SharePoint 2013 on-premises" (without mentioning Foundation or Server).

Hi Lemesnil,
The Office Web App server should support the Edit licenses for SharePoin Foundation 2013, Office Web App is free to
download, you can also try installing and configuring in a test environment, see more from the below article applied to SharePoint Foundation 2013.

Installing Office Web Apps Server 2013 fails with app-crash during install.

Hi Folks,
I am trying to install Office Web Apps Server 2013 with SP1 on Server 2012 R2. The installation gets half way through then crashes (it just says a problem has occurred).
The Event log only contains the message:-
MsiExec.exe version .5.09....
Faulting module name: Kernelbase.dll
Exception Code 0x306d7363, Faulting process id: 0x774.
Does anyone know how to install this product on Server 2012 R2?

Hi,
I’m afraid that this case is off-topic in this forum, About installation of Office Web Apps Server 2013, I suggest you posting your case to

Office 365 instead of Office Web Apps server?

We don't have an Office Web Apps server deployed. We'd really like to share Powerpoints in Lync with the full user experience, but we don't want to install a standalone server just for Office Web Apps since we wouldn't use it for anything else. We
use Office 365, is there a way to use an FQDN from Office 365 and point to that in topology builder as our Office Web Apps server? We area always loading PowerPoint from the cloud anyways. Is there any way to get around installing a stand alone
OWAS server?
Thanks,
Brandon

No as of today I believe that with Lync server 2013 on premise you do need office web app server on premise

Office Web Apps server not working externally

Hopefully someone with a functional OWA server can help. When my users try to share a presentation, whiteboard, or poll as an external user or to an external user (coming through Edge), the content fails to share and this error occurs:
"We can't connect to the server for presenting right now"
The server functions internally fine and content shares perfectly. The OWA server has a certificate from an internal CA and it is published through a TMG reverse proxy. When I hit the discovery URL, it works fine and triggers the reverse proxy
rule. However, when I try to share content, it does not hit the rule.
Thanks for your help!
Jim

Hi,
Looks like the external lync clients can't connect the office web app server. So please check if you publish the web office app to internet correctly.
Please refer this document about Publishing Office Web Apps Server Using a Reverse Proxy Server:

Office web apps "Server error in '/wv' Application"

Hi, I successfully installed office web app for sharepoint 2013. However, when I tried to open documents, it shows the preview but once view/edit in browser, I got this error. What seems to be the problem?
Server error in '/wv' Application.
Unable to determine zone from request

Hi ,
According to your description, my understanding is that you encountered the error “Server error in '/wv' Application. Unable to determine zone from request” when you open document using Office Web Apps.
Are you using https:// to access the Office Web Apps server? Is the default zone of your web application in Alternate Access Mappings using http:// ?
If so, you can change the default zone
of your web application in Alternate Access Mappings to use https:// .
Or set AllowOAuthOverHttp to true:
$config = (Get-SPSecurityTokenServiceConfig)
$config.AllowOAuthOverHttp = $true
$config.Update()

Office Web Apps Server to One Webapplication

having a farm with 2 WebApplications -> WebApp1 and WebApp2
I would like to have only WebApp2 to utilize the Office Web App server and not the WebApp1 ..
Is this possible?

Office Web apps gets registered to the whole farm, but you can modify the settings on all the site collections in Wb App 2 so they don't open in browser by default. With that setting documents will open on the desktop client and not in Office Web Apps.
Here's an article that discusses how to change the setting.

Office Web Apps Server SSL Certificate

Hi
I am deploying Office Web App Server for Integration with Lync 2013. I opted for secure communication with SSL Certificate. I want this server available to internal and external users.
I am little confused over CA for Issuance of SSL Certificate. On most of the forums, I found SSL Certificate to be issued by Internal CA. If so, will this also work for external users?
If not, then plz guide me for Generating Certificate Request on Office Web App Server to be submitted to External CA for Issuance of Certificate.
Regards.

Office Web Apps Server - Access is denied

Hello,
I was able to create an Office Web Apps server and was able to create a new farm for that server all without any issues, everything works great.
Unfortunately right after creating the farm, when attempting to run any other related powershell commands such as:
Get-OfficeWebAppsFarm
Remove-OfficeWebAppsFarm
I get this error in powershell:
Get-OfficeWebAppsFarm : Access is denied.
At line:1 char:1
+ Get-OfficeWebAppsFarm
+ ~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [Get-OfficeWebAppsFarm], SecurityAccessDeniedException
    + FullyQualifiedErrorId : System.ServiceModel.Security.SecurityAccessDeniedException,Microsoft.Office.Web.Apps.Adm
   inistration.GetFarmCommand
Although everything is actually working on the server, I'd like to be able to use those other commands in the future so I can check configurations, use "Remove" for running updates, etc... Unfortunately it appears as though this Access is
denied error may interfere with those activities.
Has anyone seen this before?
Thank you

Hi,
According to your post, my understanding is that you failed to run any other related powershell commands after creating the farm for Office Web Apps server.
If the account trying to get OfficeWebAppsFarm does not have local admin access on the machine you will simply get an “Access is denied”.
Please make sure you have the permission to run the commands.

Office Web Apps Server Certificate For External

Hi guys,
I am requesting a DigiCert certificate for my environment Exchange 2013.
Can I include the SAN name for Office Web Apps server, such as externalowa.domain.com in to the Exchange generated certificate?
From theory wise it seems logic, but kind of uncertain.
Thanks and Regards,
Low.

Hi Nithyanandham,
Thanks for the prompt reply
I will just list down what I did to be more clear.
I generated a CSR from Exchange 2013 with the following
Webmail.domain.com - for Outlook Web Access, Outlook Anywhere, ActiveSync
Autodiscover.domain.com - for AutoDiscover purposes
Can I include the externalowa.domain.com, which is for Office Web Apps server
Reason is because the Exchange server and Office Web Apps server is located differently. Am I doing the correct way?
Thanks and Regards,
Low

Office Web Apps Server IIS site disappeared?

I deployed an Office Web Apps server on a dedicated VM to be used for Lync 2013. After the initial installation / set up, I confirmed the discovery URL. It worked fine.
However, after one point in time, PowerPoint Presentations stopped working. When trying to share a PPT presentation, the Lync client popped up a message saying "Sorry, we couldn't upload <ppt file name> because we're having trouble connecting
to the service. If this keeps happening, try contacting your support team". I've done many many Lync and Office Web Apps install myself previously, and never had a message pop up like the one I saw in this case.
I tried going to the Web Apps discovery URL again, and it didn't get anywhere. I got on the Web Apps server and all the IIS sites were wiped.
I tried uninstalling the Office Web Apps server and reinstalling, but from that point on, IIS sites for Web Apps just would not appear under IIS manager.
Has anyone had similar issue with Office Web Apps?
Thanks,

Hello,
Maybe the windows update is active and configured to Automatically download and installed update of Office Web Apps and this behavior just breaking your setup.
Try
remove the farm of WAC
Install SP1
and start new deployment of farm.

Office Web Apps server security question

Hello,
According to this technet article Microsoft appears to recommend against allowing both external and internal users access to your OWA server.
http://technet.microsoft.com/en-us/library/jj219435(v=office.15).aspx#viewers
"Files that are intended to be viewed through a web browser by using Online Viewers must not require authentication. In other words, the files must be available publicly because Online Viewers can’t perform authentication when it is retrieving files.
We strongly recommend that the Office Web Apps Server farm that you use for Online Viewers is only able to access either the intranet or the Internet, but not both. This is because Office Web Apps Server doesn’t differentiate between requests for intranet
and Internet URLs. Somebody on the Internet could request an intranet URL, for example, causing a security leak if an internal document is viewed."
Just trying to make sense of this. I am building a new Lync 2013 environment and I definitely want my internal users to be able to leverage the OWA server. So does that mean I should not publish that server to the internet? And if I do
not, does that mean my users will not be able to share a powerpoint presentation at all to external users? If this is all true and I'm understanding this correctly, does this mean that most implementations choose one or the other? Or does Lync not
use these "Online Viewers" so I can just disable them and users will still be able to share powerpoint presentations with external users?
Thanks for any help you can provide for this confusion.

No, you should publish to both internal and Internet on the same server, it's just how it's done with Lync. You can't really have two with Lync for this purpose anyway. Users will upload PowerPoint presentations to it when it's time to share,
no editing is possible, and the risk is generally minimal. You can shorten the cache time to help if you're concerned.
Regardless, from the article:
http://technet.microsoft.com/en-us/library/jj219442(v=office.15).aspx setting OpenFromUrlEnabled "Turns on or off the ability to use Online Viewers to view Officefiles from a URL or UNC path.". This is set to false and turned off by default.

Office Web Apps server for Lync DNS question

We are going to deploy an Office Web Apps server for our Lync 2013 clients, available internally and externally. We do not have a split-horizon DNS so it is not possible for wac.foo.com to have a different IP for internal vs. external clients. What is the
best setup for our scenario? It looks like we can only add one address in the Lync topology builder, so would it make sense to send everybody to the external wac.foo.com regardless of whether they are internal vs. external? Or is there a better option?
Thanks,
Matt

It might be easiest to use pin-point DNS. Create an internal zone called wac.foo.com with a blank A record that points to the internal IP address of the OWAS/WAC server. This way, wac.foo.com will resolve to the correct
internal address, but you're not setting up a split zone for the rest of foo.com.
This trick can come in handy for publishing other items without recreating the entire zone, it's a nice one to keep in your back pocket.

Office Web Apps Server Default language.

we are using Office Web Apps Server 2013 SP1 with SharePoint 2013 SP1. All servers use English UK regional settings, all SharePoint Sites use English UK as default regional setting.
When we create a new document using Word Web App, the default proofing language defaults to En-US.
How can i configure the office web apps or SharePoint to use English-UK as default.

Hi talwar,
As I tested in my environment, I couldn’t set default proofing language in Office Web App. And I found a similar case:
