Office Web Apps Redundancy

I have Office web apps running on my SharePoint installation.
The question i have is this
If my OWA server goes down how do i configure SharePoint to use the client automatically instead of falling over when handling documents.
the libraries are set to Use the server default(open in browser).So currently if the OWA servcer goes offline then it would require a administrator to change the server default, is there anyway this can be automated so that is the case of the OWA server
going offline. the client will be used?

You can install two OWA servers. then register your sites with the other server when one goes down. It's the same procedure as when you originally setup the connection between SharePoint and OWA.

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.

Office Web Apps is not working

Hi,
We have tried to deploy Office Web Apps Server but, after a number of tests, we haven't been able to view PowerPoint presentations. We tested "everything" but it didn't work.
Finally, to simplify and focus the problem, we just deployed Office Web Apps Server "on its own", that is: just Internal URL, HTTP, Open From URL Enabled and sharing docs from a shared folder in the same server. So we have:
\\wacserver\share\<Docs> (Excel, Word and PowerPoint)
http://wacserver
They work both "/hosting/discovery" and "/op/generate.aspx".
If we try to view Excel doc, it works. If we try to view Word or PowerPoint, id doesn't work.
For PowerPoint, it appears the PowerPoint Web Apps frame (FILE, START SLIDE SHOW, SLIDE - OF -, NOTES...) and, in the center, an animation
"PowerPoint Web App .....". After a couple of minutes, it stops with "Either you've lost network connectivity or our server is to busy to handle your request".
What we have seen from different sources:
FIDDLER
======
/op/view.aspx?... Response 200

There were some folders and registry keys Network Service was trying to access with ACCESS DENIED response. We gave it permissions and they disappeared.
SYSTEM is trying to access some registry keys (SpellingWcfprovider.exe => HKU\S-1-5-18, ImagingService.exe => HKLM\Software\Microsoft\Windows NT\CurrentVersion\Image File Execution Options, and 2 or 3 more). It gets an ACCESS DENIED
but SYSTEM, we have checked, has "Full control" permissions in those keys or folders.
These errors appear by Office Web Server running itself, although we are not making a PowrPoint file request.

Several times, it tries to find the PowerPoint presentation in the caché, doesn't find it, manage to get it but, when trying to put it in the cache, it receives a disk space error:

The cache folder has enough disk size and PowerPoint.pptx file is just 30 KB.
It repeats this flow 3 times (as for the first HTTP requests).

pid).
We have tried a number of things but none has worked. The farm has just one server and it says ist's unhealthy. We have Windows Server 2008 R2 SP1. We have read some ways to fix the health, like HTTP Activation feature, but it only works
for Windows Server 2012 as fas as we know.
Has anybody experienced something like this or have a posible solution? Office Web Apps Server should be so easy to deploy but we have spent a lot of time with this.
Thank you very much. Your help will be very appreciated.
Kind regards.

Hi John,
According to your description, my understanding is that you cannot view the PowerPoint files in Office Web Apps in SharePoint.
Was there any error when you view the PowerPoint files in Office Web Apps?
You can troubleshoot the error following the link below:
http://technet.microsoft.com/en-us/library/ff431687.aspx#tshoot
I also recommend to re-configure SharePoint to use the Office Web Apps Server to see if the issue still occurs.

Error while creating farm for Office web apps

Hello.
I have error while creating office web apps fars.
when I enter this code to powershell : New-OfficeWebAppsFarm -InternalURL "http://servername" -AllowHttp -EditingEnabled
It says this:
New-OfficeWebAppsFarm : The term 'New-OfficeWebAppsFarm' is not recognized as the name of a cmdlet, function, script
file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct
and try again.
At line:1 char:1
+ New-OfficeWebAppsFarm -InternalURL "http://office" -AllowHttp -EditingEnabled
+ ~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : ObjectNotFound: (New-OfficeWebAppsFarm:String) [], CommandNotFoundException
+ FullyQualifiedErrorId : CommandNotFoundException
so what's the problem?

That is an error I would expect with the account running the cmdlet not having local administrator rights to the server.

Exchange Office Web Apps Preview Does not work in OWA (web)

I have setup Exchange 2013, Lync 2013, SharePoint 2013, IIS as a Reverse Proxy Server, an Office Web Apps Server, etc, etc. Everything is setup to use SSl (https) and everything works great EXCEPT... Office Web Apps... and ONLY via Exchange and OWA (exchange
browser-based access).
I can login via the intranet or Internet for everything (SharePoint, Outlook, and Lync) and Office Web apps functionality works flawlessly for all... except for Exchange and OWA.
If I login in to a web-based Exchange seeion, everything works right and I can see the various attachments.
For all other scenarios, Office Web Apps works (SharePoint, Outlook, Lync, etc), but in owa (web version of Outlook) I see that Office Web Apps is triggered (I see the Office Web Apps text and the dots that indicate something is loading)... However, it just
crashes and eventually times out (see image):
If I look in the error logs for the Web Apps Server I see this:
Essentially, it looks like that owa uses a distinctly different path to load the attachments into the Web Apps Server such that the file is not found!
What is happening? Why does Exchange OWA (web version of Outlook) somehow use a different path that fails to locate attachments in Office Web Apps, but Lync, Outlook, and SharePoint (both in Intranet and Internet) work perfectly?
This is VERY frustrating. Can anyone help?
Please?
Clearly, the reverse proxy is working, the certificates are working, OAuth is working, etc. It seems there must be some variable/path that is only defined in Exchange for OWA that uses a different path for Office Web App attachments and that path is WRONG!
Please, help!
Thanks

Sorry, something went wrong - Open Office File from Search Results Page with Office Web Apps

Hi,
I'm getting "Sorry, something went wrong" error when I'm trying to open any office document from inside Search Results Page with Office Web Apps, the same error is appearing in the document preview as well.
The error in SharePoint logs says that the file cannot be found.
Please note that this error is coming only when the "Filename" of the document is not written in English (in my case its written with Arabic characters).
If I try to open it from the document library, its opening properly with no errors.
The only difference between two URLs (document URL in Search Results and in Document Library) is the value for "sourcedoc" attribute;
In the case of Search Results page, the filename in "sourcedoc" attribute is kept as is with Arabic characters.
While in the Document Library, the filename in "sourcedoc" attribute is converted into different characters (something like: "B9%D9%85%D9%8").
Anybody have an idea on how to overcome this issue, implement a workaround or modify the "sourcedoc" behavior?
Thanks in Advance.

Dear Wendy,
Thanks for your efforts, I already tried your last suggestion before, but this didn't solve my problem.
Actually my end users are accessing this portal using ADFS and HTTPS.
Finally I got this solved, I have done below to get my overall solution working perfectly:
- First I have configured Windows Authentication and ADFS Authentication on the same zone which is the default zone.
- The issue when opening office documents with Arabic file name has disappeared as a result of first change.
- Then I have faced an issue where we are not able to crawl content under Default zone, however we have to do so, after too many efforts, I found that its related to the Load-balancer/proxy, I have made the crawler server
to crawl himself (http://CrawlServerName:PortNumber).
- Also a change on Alternate Access Mapping was needed, I have set one of the extended zones (which is running Windows Authentication only) as Internal URL for the Default Zone, and this is was the URL I used for Crawling.
I have configured Server Name Mappings to make sure we got proper URLs in Search Results.
- Then we faced another issue, which is Authentication selection on login page (How to bypass this page, and authenticate using ADFS auto), I used this solution (Set Custom Sign In Page):
http://0ut0ftheb0x.wordpress.com/2014/01/04/skip-the-authentication-selection-page-at-_logindefault-aspx-in-a-mixed-authentication-environment/.
- I faced one more issue as a result of above workaround; Sign Out functionality wasn't working well; users get logged in automatically whenever I click on Sign Out. I solved this by modifying the "Sign Out" Control under _layouts;
I made it to redirect users to ADFS Sign Out Page instead of SharePoint Sign Out Page (I know its not recommended, but I don't have any other option).

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 2010 on SharePoint 2010 site running in SharePoint 2013?

We're in the process of moving a SharePoint 2010 site over to SharePoint 2013. The SharePoint 2010 site is using classic authentication, and it's not in scope to update this to claims-based authentication.
I'd like to continue running the site in SharePoint 2010 mode without upgrading it to 2013. In this case, can I continue to use Office Web Apps 2010 for this SP2010 site? I've already installed Office Web Apps 2013 on another server but just
read that it needs claims-based authentication.

If you want to use OWA once the site has been moved to 2013 you will need to change the web application to use Claims. OWA in 2013 requires that and will not work in classic mode.

SharePoint 2013 and MS Office Web Apps - error in sharepoint's url calls OWAps

I have new SharePoint 2013 Server farm and one dedicated Office Web Apps (OWAps) server.
This farm is placed in one domain (Acompany.local). There is other domain BCompany.local whitch has both trusted to first domain (two diffirent forests, two company's branches).
Users from second domain BCompany.local well see intranet portal, build in sharepoint in the first domain (url like http://intranet.Acompany.local).
But, when they try to use OWAps, f.e. whatching preview or try to open docs for edit in browser - they see error in frame.
I'm looked it in google chrome's developer tools and find' that sharepoint use wrong url to call OWAps - like http://owaps/... instead of http://owaps.Acompany.local/...
When I created new office web app farm by:
New-OfficeWebAppsFarm -InternalURL "http://owaps.Acompany.local" - ExternalURL "http://owaps.Acompany.local" -AllowHttp -EditingEnabled
And in sharepoint farm new SWOPI binding by:
New-SPWOPIBinding -ServerName "http://owaps.Acompany.local" -AllowHTTP
Get-SPWOPIBinding tell that all SWOPI bindings are http://owaps.Acompany.local, but in devtools I continue to see wrong http://owaps/... url
Any idea to fix this behavior?

The reason WAC is recommended to be installed on a dedicated server is that it recreates the IIS sites/settings. This is why you're seeing the setting reset itself after restart.
What I'd probably recommend is creating a script that queries the WAC URL on a regular basis.

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.

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.

Hi,
Thanks for your posting in this forum.
I have moved this thread in Lync Server 2013-Management, Planning, and Deployment forum for more dedicated support.
Thanks for your understanding.
