Single Reverse Proxy and multiple Office Web App Servers

Hi all,
I have recently installed a new office web apps server pool in my new location and configured it in my Lync topology as well.
I have a single Reverse Proxy (IIS ARR). Inside my Reverse Proxy I have created a new web farm for my new web apps server. The configuration of old web apps server. I have copied the settings from my old web app's web
farm in IIS including its Inbound rule regular expression.
Now when I try to upload a powerpoint as an external guest hoping to hit my new web apps server, my reverse proxy tries to hit my old office web apps server and no traffic is sent from reverse proxy to new web apps.
my reverse proxy shows the health of the new farm as healthy.
should the inbound rules be different for these farms in reverse proxy?
Any suggestions are welcomed.
Thanks,

Hi,
In addition to Luca's comment in order to determine if the farm is actually working correctly in the first instance, did you disable or remove the old server farm?
Can you also confirm that there are no static routes in place on the IIS ARR box?
Kind regards
Ben

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.

MS ISA Reverse Proxy and access to webgui apps

Hi All,
We have an EP7 system that is connected to backend ECC and BI systems. External users now need to access EP via an MS ISA server that acts as a reverse proxy.This works fine when accessing EP itself, but not when accessing webgui iviews that point to the backend ECC system, as the generated absolute url contains the backend hostname which is not resolvable from the external browser. We have edited the ECC system properties in EP to point to the external url instead of the ECC hostname, and in the browser I can see that it points to https://publicurl.company.com:8000/sap/bc/*. However, we get 'IE cannot display the page..' errors in the browser. What are we missing here?
Regards,
Mark

Hi Mark,
First of all you need to configure ISA as a reverse proxy to your ECC system as well as to your portal, perhaps using a different address for the same server, e.g publicurl.company.com for the portal and ecc.publicurl.company.com for the ECC system.
Next, you need to make sure that internal access to ecc.publicurl.company.com will also go to ECC, possibly by setting up a local DNS entry.
Finally, you should edit the system entry for ECC in the Portal and set the ISA, WebAS and ITS hostnames to be ecc.publicurl.company.com.
As you can see, this is primarily an infrastucture problem rather than a portal problem...
Hope this helps,
Darren

Can a single instance of iPlanet Web Proxy act as a reverse proxy for multiple internal web sites?

Hi Dave,
You should be able to create multiple reverse mappings.
Refer to the following technotes and see which scenario applies to your specific case:

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

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:

High availability for Lync 2013 persistent chat server and office web app server

I have 1500 users, need HA in primary data center and DR also. looking for HA and DR solution for persistent chat server and office web app server.
is below correct?
1. 2 persistent chat server in a pool of primary data center and 1 in DR. can this be reduced or any changes?
2. 2 Office web app server in a pool of primary data center and 1 in DR. can this be reduced or any changes?
also do i need HLB for both roles?

1) In Lync Server 2013, there are improvements in both high availability and disaster recovery:
High availability improvements: SQL Server mirroring is used to provide high availability for the Persistent Chat Server content database and Persistent Chat compliance database within a data center (in-site).
Disaster recovery improvements: Persistent Chat Server supports a stretched pool architecture that enables a single Persistent Chat Server pool to be stretched across two sites (that is, a single logical pool in the topology, with servers in the pool physically
located across two sites). SQL Server Log Shipping is used for cross-site disaster recovery.
For more information about high availability and disaster recovery, see
Configuring Persistent Chat Server for High Availability and Disaster Recovery in the Deployment documentation.
2) for HA & DR, you can 2 Office web app server in a pool of primary data center and 1 in DR. and You will need HLB for office web app servers

Load balancing and HA for office web apps server Lync 2013

Hi,
I have 12000 users, 3 FE servers in a pool, 2 edge server in a pool, HA required, IM/presence, A/V, WEb conferencing required. plan to have 2 office web apps server a farm with HA, below are my queries
1. which type of load balancing i need....DNS or HLB for office web app servers? if its HLB then is it mandatory?
2. i have already 2 HLB for FE pool .. one for externa url , one for internal URL...can i use the same HLB for office web app servers ?
3. one more question regarding EDGE pool load balancing, can i use the same HLB in EDge pool also that i am using for FE pool?

Hi,
1. which type of load balancing i need....DNS or HLB for office web app servers? if its HLB then is it mandatory?
WebApps runs on https and you cannot load balance http traffic using DNS load balancing. you need to have a HLB.
2. i have already 2 HLB for FE pool .. one for externa url , one for internal URL...can i use the same HLB for office web app servers ?
you can use the same HLB for that
3. one more question regarding EDGE pool load balancing, can i use the same HLB in EDge pool also that i am using for FE pool?
for that one, you probably need a separate HLB.

Office Web Apps (OWA) deployment and licensing

Hi,
Im trying to get some info about how to eventually purchase and install Office Web Apps (View only) for all Sharepoint-users in the farm.
As from 22/10 -14 OWA is no longer available for download from Microsoft Download Center.
Source: Technet
They're redirecting users to the Volume Licensing Service Center, but the link is dead.
What i found searching is this page with lack of info: http://www.microsoftvolumelicensing.com/ProductPage.aspx?pid=387
I feel stupid, but this page says nothing to me.
Is there any obvious way to calculate the cost of OWA?
Does OWA even cost if the organization is just going to View but not edit?
From where should i get the installationpackage now when Microsoft Download Center got rid of it?
Kr,
Rasmus

Hi,
Office suite licenses(Standard or Pro Plus) are only required for those employees editing Office Web Apps documents.
The Office Web Apps are included when you purchase Office Professional Plus 2013 or Office Standard 2013 licenses and allow you to
view and edit Office files using the Office Web Apps Server.
Office client suites are licensed per device. The primary user of a device licensed for this Office software is licensed for access to the online companion Office Web Apps from any device. In these situations, the primary user is enabled for remote online
access through Office Web Apps.

Error word web app can not open this document for viewing in office web apps 2010

and installed office web apps 2010 and sp2
adil

Hi Adil,
From the error message, I recommend to check the things below:
Check if Word Viewing service is started in Central Administration. If it is started, stop and re-start it.
Check if the Word Viewing service proxy is created.
Check if the Word Viewing service proxy is associated with web application with issue.
If above cannot work, please check the ULS log for further research.

Office web Apps server Lync 2013

Hi All,
I have logged onto my Volume licensing site and could not search Office Web Apps servers for download?? I wonder how do i download it?

Hi channavera,
Office Web Apps Server was removed from the Microsoft Download Center. Now it only was available for
download under Volume Licensing agreements. For more information please read the FAQ below or visit the site Volume Licensing
Service Center.
FAQ
Why is Web Apps Server being removed from the Microsoft Download Center?
VLSC is best suited as the location from which to serve all customers according to their agreements with Microsoft.
What about existing installations? Do I need to re-license them?
No. Web Apps Server installations and/or downloads that occur before 11/24/14 will continue to be licensed for free viewing.
Will there be an evaluation version for Developers and IT Pros?
Evaluation availability will continue on MSDN for subscribers. Additionally, Volume License agreements allow for product evaluation.

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>

Victoria

Office Web Apps broken in IE11 after CU installation

We just installed the Oct 2013 CU and during testing found that Word and PowerPoint Office Web Apps now do not work in IE11 only. IE 8-10, Firefox, Chrome, and Safari all still display documents fine using Office Web Apps. Excel Web App doesn't display
an error, but it also seems to have issues and doesn't always display the ribbon menu with IE11 only.
The error being displayed is "Sorry, we ran into a problem"
Does anyone have any ideas on what is causing or has seen a similar issue?
Thanks.

There are posts about problems with SP & IE 11 all over the place. It's a known issue. Most of the problems can be solved by changing the compatability mode in IE. Here's some links you can check out:

SharePoint 2013 cannot view PDF documents in mobile browser with office web apps

Hi,
I'm receiving the following error when viewing SharePoint 2013 PDF documents in a mobile browser after clicking on the filename:
"Viewing of .pdf files has been disabled in Microsoft Word Mobile Viewer. Please get in touch with your helpdesk."
My Question
Is viewing PDF documents in mobile browsers with Office Web Apps SP1 actually supported? If so, how can I enable it? I've already have pdf viewing working in non-mobile browsers. Word documents open just fine on mobile browsers too.
I'm getting conflicting answers for pdf mobile viewing support from various sources:
You've got Microsoft toting that they've added in PDF viewing on any device for Office Web Apps
http://blogs.office.com/2013/07/03/pdfs-in-the-word-web-app/
A MS support person saying saying it is not supported
http://blogs.technet.com/b/office_web_apps_server_2013_support_blog/archive/2013/12/31/enabling-pdf-previews-in-document-libraries-with-office-web-apps-2013-in-sharepoint-2013-open-link-does-not-work-from-preview.aspx
Another person implying that it should work because you can disable pdf browsing for mobile browsers only
http://blogs.technet.com/b/office_resource_kit/archive/2013/07/24/control-whether-pdfs-open-in-word-web-app-or-the-default-pdf-reader.aspx
What I've tried
When I started looking into this there was a mobile WOPI entry:
Application     : WordPdf
Extension       : PDF
ProgId          :
Action          : mobileView
IsDefaultAction : False
ServerName      : 20SP8
WopiZone        : internal-http
I tried experimenting with tweaking this binding by changing the DefaultAction to true, and even removing it altogether via:
Get-SPWopiBinding -Action "MobileView" -Application "WordPDF" | Remove-SPWopiBinding -Confirm:$false
But I still get the same message.
I removed all the WordPdf bindings and re-added them via:
New-SPWOPIBinding –ServerName "<myserver>" –Application "WordPDF" -AllowHTTP
No dice. In fact the mobileview binding doesn't even come back... but I guess that is a different issue altogether.
Version
SharePoint 2013 (SP1)
Office Web Apps Server (SP1)
Farm Setup
Internal facing only
2 front end servers, 1 app server, 1 office web apps server

I think the PDF support, if it exists, in only in Office 365. Always remember that the Office 365 and on premises versions will never be in sync. On premise is updated using periodic service packs and Office 365 has continuous updates. (I've heard every
10 days.)
In my Office 365 / IE 10 tests, the PDFs open in the browser's default PDF viewer, in my case FoxIt Reader. So I can't prove one way or the other about support in Office Web Apps.
