Office Web App - Use for viewing but not for editing

Hello,
i'm searching for a possibility to use the web app server only for viewing documents but not for editing.
I want to accomplish this for docs and ppts.
So the possibility to edit in Web App should be greyed out or even better, vanish completely.
Best regards
Stephan

You can remove the bindings for OWA for some actions.

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 - how to disable office web apps features for one web application

ENV: Sharepoint 2010 farm with office web apps + fast search
I have the requirement for one web application to open all its documents in client applications - I can enable feature "OpenInClient". This web application uses team site template and other web application also uses team site template. ( feature
stapling ruled out) Now I can run powershell cmdlet to enable this feature on all the currently existing site collections. But the requirement is to enable this feature for all the future site collections. This web applications has 60 k site collections
and atleast more than 10 site collections get created each day and they dont like the option to run a powershell script each day to activate this solution.
Is there any other way to by default activate new site collections on this WA to open in client applications by default (can we disable this office webapps features only on one web app)?
VM

I have learnt from this forum that it is not possible to turn off Office web apps on single web application. The line of control lies at farm level and then at site collection.

Office Web App Prompting For Credentials Externally Only

We deployed an office web app server and it works great internally, but whenever we try to access documents externally, we are prompted for credentials. Even if we put our credentials in, we always get a 401 forbidden error. Also note that
we can access the hosting/discovery page fine internally, but not externally. Any help is appreciated.

Hi,
According to your description, I think this issue is more related to SharePoint, I suggest that you could post it to

Office web apps Server for Sharepoint 2013

Hello,
I used the following article to install office web apps server and hook it up to a test sharepoint server:
http://technet.microsoft.com/en-us/library/jj219455(v=office.15).aspx. The OWAS service was verified as working by loading:
https://owas.companyname.com/hosting/discovery
For the sharepoint configuration phase, the following commands were run on the sharepoint machine:
1) New-SPWOPIBinding -ServerName "owas.companyname.com" -- (owas.companyname.com) is the host name of the owas server)
2) Get-SPWOPIZone
3) Set-SPWOPIZone -zone "external-https"
However, office documents are still launching in the desktop office applications, not in the browser. Any ideas of what else I may need to do?
thanks,
Sherazad

Hi ,
According to your description, my understanding is that you fail to configure Office Web Apps for your SharePoint 2013.
How about run Get-SPWOPIZone? If you can get a result, it says that your SharePoint have connected with Office Web Apps.
Then you can run below command to change the zone to internal-https.
Set-SPWOPIZone -zone "internal-https"

Office web apps is working in Chrome not in IE

When I attempt to open a document using office web apps in IE, its throwing error like "sorry there was a problem and we can't open this document", I I open the same document using google Chrome I can able to open and edit the document too?
Any help please?
Thanks,
-Sendil

Hi,
I understand that you fail to open a document using office web apps in IE, but the document can be opened in Google Chrome.
I can suggest you to reset Internet Explorer settings. If system is Windows 8, we can
follow these steps:
Swipe in from the right edge of the screen, and then tap or click
Search. Enter Internet options in the search box, and then tap or click
Settings.
In the search results, tap or click Internet Options. Tap or click the Advanced tab and then tap or click
Reset
In the Reset Internet Explorer Settings window tap or click Reset
Close and then restart Internet Explorer for the changes to take effect.
If system is Windows 7, Windows Vista or Windows XP, we can reset Internet Explorer automatically.

Office web app error for one note only

There is strange error in my SharePoint 2013 farm with OWA. Everything works fine except for one note.
If you click in the notebook on the left hand side of the site, for first time everything works fine. When you try to click the same link second time, either server error comes up in chrome and nothing in IE. If i deactivate the web feature one note and
reactivate it, it works again for first time and nothing comes up for the second time. Error i see is
WOPIFrame -Unhandled exception: System.TimeoutException: The open operation did not complete within the allotted timeout of 00:01:00. The time allotted to this operation may have been a portion of a longer timeout. ---> System.TimeoutException: The read
from the pipe did not complete within the allotted timeout of 00:01:00. The time allotted to this operation may have been a portion of a longer timeout.
Has anyone seen this behavior?

Hebrew is backward (left-to-right) in Calendar view, but not in edit mode

Hey all,
I'm wondering if there's a workaround for a bug where Hebrew appears backward in most Calendar views, for example the day and list views. If you go to edit the event, it appears correctly.
Thanks Apple very much for adding the Hebrew characters to the fonts and Hebrew support in Safari!
Thanks,
Daniel

Bump. This is happening on my iPhone too.

PowerPoint presentations not working with Office Web Apps

Hi,
I have deployed Lync 2013 and Office Web Apps Server in order to share PowerPoint presentations. All te sharings are working fine (Desktop, Program, Whiteboard, Poll) but PowerPoint presentations.
I have re-installed Office Web Apps Server several times but it doesn't work:
Discovery URL is OK
Event IDs in Lync Server Event Viewer are OK
I have checked certificate and created it twice and that's not the problem (when tried to use a wrong certificate, the behaviour was different).
Tried aspnet_regiis but didn't worked.
Both Lync Server and Office Web Apps Server are updated.
Servers are Windows Server 2008 R2 SP1.
I have tested both Lync 2013 and Lync 2013 Basic clients but no one works.
When I share a PowerPoint, I can see it follows the whole way through LyncShare, Lync Server and Office Web Apps Server. PowerPoint files get to Office Web Apps Server (different name but I can move then to other workstation and check
they are the files shared).
Clients begin showing a "Loading..." but end showing "Network connectivity lost or server too busy" (after 90 seconds more or less).
If I get URL from Lync-UccApi-0:
https://wacserver.domain/m/Presenter.aspx?a=0&e=true&WopiSrc=https%3A%2F%2Flyncpool.domain%2FDataCollabWeb%2Fwopi%2Ffiles%2F11-1-90C848&access_token=AAMFEECCjUt7489YhSlhQY4GBWcGEIsJ8vG8JQH9w0g_TTTVe3aBEECCjUt7489YhSlhQY4GBWeCApwQgyBHjXVmSaUT70sAAlMNX4oAfTt5Nqgy5sJwqlLneNAxGYYIsFS5edC90AgIDURhdGFDb2xsYWJXZWI&<fs=FULLSCREEN&><rec=RECORDING&><thm=THEME_ID&><ui=UI_LLCC&><rs=DC_LLCC&>
If I put this URL in the browser, it turns black and shows "Loading..." and, after a long while, "PowerPoint Web App...", but it remains in this state (loading) without working.
In the Office Web Apps Server Event Viewer there are some errors related to other services I'm not using, as OneNote, or for Monitoring with the "PositiveDirect" and "NegativeDirect" tokens. Machine also answers it's
Unhealthy, but as I have read, this is not a problem.
In the ULS Logs I just see errors related to these events but logs for PowerPoint work fine. And IIS is answering with "200" (although there are a number of petitions that seem to be repeated:

It seems that something is not working between the clients and Office Web Apps Server. There is not a firewall and machines see each other. Certificate is accepted.
I have tried so many thing but none of them worked.
Does anybody have an idea?
Thanks!

Hi Thamara,
There is a HLB but I thought of that and tested both: with HLB and pointing just a Front End, without HLB. In both cases, results were the same.
I can access the Front End pool web services from the WAC server using the IE.
I'm watching now this event:

In addition, as I'm making test for share PPT and they aren't finally showed, this error appears also:

Office Web Apps 2013 + could not establish trust relationship

We currently have a three tier SharePoint 2013 Farm:
1. Web Front End Server (Server 2008 R2 Enterprise) - Servername: TEST2SP013.domain.dom
2. Central Admin Server (Server 2008 R2 Enterprise) - Servername: TEST2SPCA013.domain.dom
3. SQL Server (Server 2012 Datacenter) - Servername: TESTSQL012.domain.dom
All Machines are in the same IP/Subnet.
We are trying to setup a new server (Server 2012 R2 Datacenter) (Servername: TEST022.domain.dom) to run Office Web Apps 2013 in our TEST environment to test the system before rolling in production and have had issues throughout the entire process.
The technet articles we have used are:
http://technet.microsoft.com/en-us/library/jj219435.aspx
http://technet.microsoft.com/en-us/library/ff431687.aspx
http://technet.microsoft.com/en-us/library/jj219627.aspx
We finally have what I thought was a correct setup but anytime we try to edit or view a word, excel, powerpoint document within SharePoint 2013, we receive "Sorry, there was a problem and we can't open this document. If this happens again, try opening
the document in Microsoft Word."
We found a few How-To Setup Office Web Apps sites where other people provided step-by step instructions:
blogs.msdn.com/b/sowmyancs/archive/2012/10/29/install-configure-amp-monitor-office-web-apps-2013-for-sp-2013.aspx

We reviewed the ULS logs and found the following error:

None of the article provide specific step-by-step instructions with using HTTPS in a test environment specifically when it comes to Self-Signed Certs through Active Directory Certificate Services.
We tried creating a Self-Signed Cert through IIS on the Office Web Apps Box which did not work.
We tried creating a Cert through Active Directory Certificate Services which did not work.
We tried adding the Cert through Central Admin > Security > Manage Trust which did not help.
We verified "get-spwopizone" is set to internal-https
We can access the Web Apps https://test022/hosting/discovery site and view the XML with no issue on any machine on our network.
We added our domain to the list of approved domains that can use Office Web Apps as well as add "Domain Users" as the security group that can "EDIT" Office Documents through Office Web Apps.
After each step, we tried performing either a system reboot or IIS Reset on the Office Web Appcs and WFE box.
My Question is how do we generate a certificate (either self-signed through IIS on the Office Web Apps Box or through AD) that will allow this application to work? I read that the Fully Qualified Domain Name needs to be in the SAN field of the Cert but when
we request it, I have no way of entering this information. I tried following http://technet.microsoft.com/en-us/library/ff625722 to manually request a certificate with a Custom SAN but that did not work either.
I am assuming the certificate issue is with the New Office Web Apps box. Is this correct?
-Chris

If internal cert then you will have to add certificate from OWA to tursted certificates in each sharepoint server plus add the certificate from central admin in Sharepoint through manage trust. Also you will need to install p7b file (file that contains
path to root certificate to verify each intermediate certificate) for internal cert to each sharepoint server to not get certificate error.

Office Web Apps not working externally SharePoint 2013

In the production farm we have connected office web apps server which is FQDN server name ( xxx.xxx.corp.local) , we can open the sites internally without any issues, but when we open from externally office web apps asking for authentication and not working
properly.
Please help me how to make it work in external.
Thanks, Ram Ch

You will need a public facing URL or IP address. Check below
You need to configure your OWA for internet
New-OfficeWebAppsFarm –InternalUrl "md1xxx95.jdaxx.corp.local" -ExternalUrl "http://198.xxx.xxx.xxx" -EditingEnabled

Office Web Apps 2013 with SharePoint 2013 Server

Hi All,
I have installed a separate server for Office Web Apps 2013 on Windows Server 2012 VM. I have followed TechNet's article on
Deploying Office Web Apps Server & exactly followed steps.
On SharePoint Server 2013 (Windows Server 2012), I followed TechNet’s article on
Configure Office Web Apps for SharePoint. The Office Web Apps on SharePoint 2013 environment works for
Excel document that shows “View in Browser” but
no Preview.
However, PowerPoint and Word documents doesn’t show “View in Browser”. I thought Internet Explorer 10 has some issue with Office Web Apps and checked on Chrome and results were same.
On SharePoint Server 2013 environment, I have configured 3 services applications, MMS, UPS and Excel Service.
1.) Do I need any other service applications to be enabled for OWA 2013?
I read number of blogs,
Installing Office Web Apps Server for SharePoint 2013 (Steve Mann),
Install Office Web Apps 2013 with SharePoint 2013 (Max Melcher) and Spence Harbar
(Enabling Office Web Apps Preview editing with SharePoint 2013). and all these blogs give more or less same steps that I have followed.
Strange thing is that Excel documents on my SharePoint 2013 sites are working but neither word or PowerPoint documents are not showing option for “View in Browser”.
I am using HTTP and not HTTPS.
2. Can someone please advice how could I solve the Office Web Apps 2010 on Word and PPT?
3. How to can enable preview for Excel, Word and PPT documents.
Thanks you.
Regards,
Aroh

Hi Inderjeet and Olafur,
Thanks for your reply.
@Inderjeet: That site collection feature on SP2010 works on our production environment but on SP2013 site collection there is no OWA feature. Microsoft recommends to have a separate OWA2013 server and what I create
a separate VM for OWA2013 server.
@Olafur: Your suggestion looks spot on. The OWA server does show the discovery:
Our SP2013 development server has limited RAM (4GB) and it think is causing the issue.
Let me check if increasing RAM solves the issue.
Thanks again for your suggestions. (Interjeet and Olafur).

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.

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 (2013) certificate issue

If the name of the farm is different from the name of the individual office web apps server machine is there any way to deploy office web apps server with a single domain SSL certificate?
My office web apps server is working, but reporting itself unhealthy, apparently due to the fact that the SSL cert is for the name of the farm and that is different from the name of the machine.
Errors are 2004, 1004, 2156, 1156, "could not establish trust relationship for the SSL/TLS secure channel"
Going to the farm's discovery URL in the browser works fine, but going to the machine name (plus /hosting/discovery) gives an SSL error because the name of the farm is not the same as the name of the machine.
Is there any way to make it use the farm's URL instead of the machine's URL in its own internal watchdog operations? Or any way to make it use a self signed certificate on the machine's URL for it's own health checks and still use the legitimate purchased
SSL cert for user access? Or any other way you can think of to use a $5.99/yr single domain certificate instead of a $89.99/yr multiple domain certificate?

I am experiencing this same issue. The OWA server has sp1 installed. In the OWA event logs I am getting health fails for 2 events and as best I can tell it seems to be related to this issue.
We are also using a single godaddy certificate with a non machine name FQDN. Both internal and external url's of the OWA farm are set to this same name.
The problem only seems to occur with the 'Proofing Watchdog' (See events below).
Has anyone got any update on whether this is supposed to be fixed ?
