Lync Office Web App Farm External Access using IIS ARR

When i try to present a powerpoint app when logged in externally i get an error saying that it could not connect to the office web app server. I need some help with (maybe screenshots) of what the reverse proxy settings should be. Here is some info
so maybe someone can fill in the blanks.
My Office web app server has a private address and sits on the inside. The DNS name is owasrv.mydomain.com
The internal url is https://owasrv.mydomain.com
The external url is https://wacsrv.mydomain.com
i have a public A record pointing to wacsrv.mydomain.com and my ssl cert has a SAN entry for wacsrv.mydomain.com
***NOTE our public and private domain names are the same...that is not a mistake.
I mostly need help with the what to put in for the url rewrite rules and what to put in when creating the server farm. Also is it OK that the name of my server is different than the external url address.

Hi Gerald,
Did you follow this guide here http://blogs.technet.com/b/nexthop/archive/2013/02/19/using-iis-arr-as-a-reverse-proxy-for-lync-server-2013.aspx
and mainly the section down the bottom which refers to publishing the WAC by matching this pattern ((?:^en-us/|^hosting/|^m/|^o/|^oh/|^op/|^p/|^we/|^wv/|^x/).*)
and moving the rule to the top?
What happens when you try to browse to https://wacsrv.mydomain.com/hosting/discovery from external?
They can be different, I usually make them the same for simplicity, but as long as they're set on the Webfarm it shouldn't be an issue.

Office Web Apps farm - how to make it high available

Hi there,
I have deployed OWAs for Lync 2013 with two servers in one farm. When I was testing, e.g. the case when other server is down I found out the following error:
Log Name:      Microsoft Office Web Apps
Source:        Office Web Apps
Date:          17/03/2014 22:59:54
Event ID:      8111
Level:         Error
Computer:      OWASrv02.domain.com
Description:
A Word or PowerPoint front end failed to communicate with backend machine
http://OWASrv01:809/pptc/Viewing.svc
Does that means, that OWAs cannot setup as high avaiable when using standalone OWAs only? Above error appeared when the server OWASrv01 was rebooting.

Hi Petri,
For your scenario, you have achieve a  high performance for your Office Web Apps farm but not high availability.
For performing a high availability Office Web Apps farm, you can refer to the blog:

Office Web Apps Farm Across Multiple Data Centers?

I have not been able to find any definitive information about this but the article below seems to suggest what I have in mind is not recommended. I am not sure about supported.
"Stick to one data center. Servers in an Office Web Apps Server farm must be in the same data center. Don’t distribute them geographically. Generally you need only one farm, unless you have security needs
that require an isolated network that has its own Office Web Apps Server farm."
http://technet.microsoft.com/en-us/library/jj219435.aspx#topology
What I have is two very well connected data centers located in the same metro area. We will be deploying a Lync EE pool at each site and use pool pairing for DR. What I am wondering is should I:
Create a single Office Web Apps farm with the server from each data center as members?
Create a farm in each site with a single member, but both farms sharing the same URL?
Create a farm in each site with a single member, but both farms have different names. This seems unnecessarily ugly, but throwing it out there.
Since Lync is using Office Web Apps in read only mode the question is different than if SharePoint were involved. However, I can't rule out this farm also being used for SharePoint down the road.
The LB/RP device of choice is Citrix NetScaler. Another thought I had is can that be configured so incoming requests for Office Web Apps at each data center can prioritize traffic to the server or farm within that data center? If that is unavailable
then switch to the server at the other data center?
Thanks.

Hi,
An Office Web Apps farm can be deployed to provide functionality for multiple sites.
Also you can deploy one Web Apps farm on each site.
So I think you can choose to deploy with the option one and three as you said.
Here is a case about deploying Lync deploy Office Web Apps server may help you:

Office Web Apps Farm - undo the AllowHTTP switch

I allowed HTTP while troubleshooting a cert issue, only to discover that the argument doesn't take a $false option.
It seems to be enable-only. Now I want to disable it. Can I do this via PS or must I do a registry hack?

Try:
set-OfficeWebAppsFarm -AllowHttp:0
or
set-OfficeWebAppsFarm -AllowHttp:$false
Notice the ":" instead of a space.

Office Web Apps server / Lync server 2013

Hi I have installed a Lync 2013 Server and Office Web Apps Server. Configured Lync topology, Office Web Apps farm and certificates.
However when i start the services i get this error message in the log saying Office Web Apps discovery failed.
Event ID: 41033
Description:
Office Web Apps Server (WAC) discovery failed, PowerPoint content is disabled.
Attempted Office Web Apps Server discovery Url:
Received error message: Invalid Uri syntax for WAC configuration
The number of retries: 1,
Cause: Office Web Apps Server may be unavailable or network connectivity may have been compromised.
Resolution:
Check HTTPS connectivity from this box to the Office Web Apps Server deployment using the discovery Url.
I can access the OWAS server Url from Lync Server
Connecting to the HTTPS discovery URL is working fine, and brings up the XML-page (after i click "show all content").
The two servers are located on the same internal network, DNS resolves fine both ways, and no firewall rules blocks any connections between the two. Can anyone please help me figure this out?
Only identical problem found online is here (Invalid Uri syntax for WAC configuration):
http://blogs.technet.com/b/dodeitte/archive/2012/09/10/office-web-apps-server-amp-lync-server-2013.aspx
He resolved the problem by assigning a new OAuthTokenIssuer certificate. This however did not fix the problem in my case.

Sverre A. Veel

Hi,
In addition, please make sure you have restarted front end and office web apps server after reissuing the certificate.

Office Web Apps 2013 Error

Hi all,
Currently we are facing a problem in our Sharepoint 2013 environment with Office Web Apps Server.
Initially we connected the Office Web Apps farm to the Sharepoint farm and it worked well, but suddenly, we are not able to see the previews of the documents in the hover pannel or openning the documents in a new window or same window (doesn´t matter). We
receive the following error message:
Sorry, something went wrong
An error has occurred on the server.
This with a correlation error code, if we search this error code in Sharepoint we find the following information:

anyone has faced a problem like that?
Thanks in advance

Stephan,
1. with the Get-OfficeWebAppsMachine command I can see that Health Status report as Unhealthy, but the reason for that is the certificate, it does not include the fqdn of the office web apps machine (Yes, I know that this is not the optimal configuration)
2. If we try to navigate trought the URL
https://..../hosting/discovery it shows the xml file of the owa server, no problem here
3. Get-spwopibinding shows all the bindings configured as default, we haven't done changes here
4. get-spwopizone = external-https the sharepoint platform is published as extranet trought a TMG, office documents can be accessed externally by WOPI server
5. I have tried both methods, with true and false with the same result, I have tried to reboot several times the WOPI server.
And for the final question, yes I have checked the event logs, but shows nothing, I think that is more a problem of Sharepoint previews than other problems

Office web App Server Not Working Properly

Hello Everyone,
We have published Office Web Apps server externally through reverse proxy and it has some issues. Now if we browse the link
https://owas.schs.sharjah.ae/hosting/discovery (Internally) or
https://owa.schs.sharjah.ae/hosting/discovery (Externally) I get the XML Page.
Now when I try to browse any other pages in the directory for example
https://owa.schs.sharjah.ae/op/generate.aspx or another Url like
https://owa.schs.sharjah.ae/m/Presenter.aspx whether it is browsed internally and externally I get the error file not found '404' but the files do exist in the directory.
No idea on how to solve this issue, any help on this matter is really appreciated.
Regards,
Sheldon
MVI - Most Valuable Indian

What specific issue are you having?
Are you wanting to use the WAC to open files using the URL? If so, have you set OpenFromUrlEnabled to true? You can
check this using Get-OfficeWebAppsFarm cmdlet and Set-OfficeWebAppsFarm OpenFromUrlEnabled $true cmdlet.
I have several Office WebApp instances that I've deployed for Lync PowerPoint sharing where the setting is not enabled and I am also unable to browse to those pages, but PowerPoint sharing works fine.

Office Web Apps 2013: SSLOffLoad, Cannot connect Sharepoint.

Hi,
Background.
We have a 2 machine SharePoint 2013 farm and a 2 machine Office Web Apps Farm, both of which are behind a load balancer. Our public DNS holds the records for the two farms: webapps.company.com and sharepoint.company.com. However these domains are not in
the internal DNS and cannot be resolved internally. I've put these in the hosts file on the respective machines, so they can talk to each other.
I'm now at the point where I need to connect SharePoint to the OWA farm. I've followed the guide here: http://technet.microsoft.com/en-us/library/jj219455%28v=office.15%29.aspx
and setup the OWA farm by the specification under the heading "Deploy a multi-server, load balanced, office web apps server farm that uses HTTPS".
My creation string
New-OfficeWebAppsFarm -InternalUrl https://machinename.domain.com -ExternalUrl https://webapps.comapny.com -SSLOffloaded -EditingEnabled
That went ok and the farm is created. I then added the second machine
New-OfficeWebAppsMachine -MachineToJoin "machinename.domain.com"
Now that the farm is created i went ahead and ran
New-SPWOPIBinding -ServerName machinename.company.com
But that just gave me "WARNING: The Server did not respond. Trying again"
Adding the -AllowHttp flag let me continue, but that ended up giving me error when i created or opened a document in Sharepoint.
So my guess is that i need to figure out why i cannot use New-SPWOPIBinding -ServerName machinename.company.com without -AllowHTTP.
It was my understanding that we don't have to setup SSL on the individual farm server as the load balanser woudl take care of that.
Any ideas as to why New-SPWOPIBinding -ServerName machinename.company.com won't work?
Thank you for taking the time to read my post
Regards.

http://social.technet.microsoft.com/wiki/contents/articles/19039.sharepoint-2013-how-to-enable-office-web-apps-to-work-in-both-internal-and-external-environments.aspx
Because I’ve not configured my OWA machine to be published to the Internet so I have to use its Internet-public IP. It’s not a recommended best practice. In your case, the external URL would be http://owa.abc.com
. Above I’m not using SSL certificate
to encrypt data over the Internet. Just add CertificateName parameter if you want to use whether CA-issued certificate
or self-signed certificate. Finally, check both internal URL (http://app03/hosting/discovery
) and external URL (http://198.xxx.xxx.xxx/hosting/discovery
) to confirm everything is working
well. Your screen should display XML structure.
Now you need to re-bind all SharePoint machines to WAC farm using New-SPWOPIBinding (http://technet.microsoft.com/en-us/library/jj219441.aspx
). Next, you just need to set the WOPI
zone for external use even there is an internal use in your SharePoint environment.
1
Set-SPWOPIZone –zone “external-http”
Finally, configure Excel service and then upload an Excel workbook into a document library and check it. Below are the screenshots of OWA working on both internal and external environment.

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 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 2013 install issue

Dear All,
when i install office web apps server in a new server(OS:Windows Server 2008 SP1) with PowerShell Scripts it keep the installing status for more than four hours .
what should i do now ,i think it should not take such long time as i do the same installing in the other server before which takes less than 1 hours.
beg your suggestions!

Hey
please take these points into your considerations:
- OWA server can be installed on Windows server 2008 R2 or Windows server 2012
- Log in as administrator and preferred to use domain administrator account specially to create new office web apps farm
- run the script
Add-WindowsFeature Web-Server,Web-Mgmt-Tools,Web-Mgmt-Console,Web-WebServer,Web-Common-Http,Web-Default-Doc,Web-Static-Content,Web-Performance,Web-Stat-Compression,Web-Dyn-Compression,Web-Security,Web-Filtering,Web-Windows-Auth,Web-App-Dev,Web-Net-Ext45,Web-Asp-Net45,Web-ISAPI-Ext,Web-ISAPI-Filter,Web-Includes,InkandHandwritingServices,NET-Framework-Features,NET-Framework-Core

Should the Edit in Browser link appear when Office Web Apps is read only?

Hi,
We have deployed an Office Web Apps farm in read only mode for licensing reasons.
There is a binding between SharePoint 2013 and the Office Web Apps farm, everything is working well, except the option to Edit Office documents using Office Web Apps is quite prominent on the ECB menus and document previews.
Is anyone able to advise whether this is expected behaviour? When the link is clicked a friendly error message states that licensing doesn't support editing, which is correct. I'm just trying to see if the user experience can be improved by a setting that
we've missed somewhere along the line.
Thanks in advance.

Hi,
Per my knowledge, if you have configured Office Web Apps for SharePoint, the Edit in Browser option will appear in the ECB menu regardless of the licensing of the Office Web Apps.
So I recommend to use CSS code to hide the Edit in Browser option if you do not want the user to use it.
Edit the page of the document library view page, and then add a Content Editor web part to the page.
After that add the code below to the Content Editor web part:
<style>
a[Title="Edit in Browser"]{
display:none !important;
</style>
Thanks,
Victoria
