OWA Blank Attachment Preview with Office Web Apps Server

Environment: Exchange 2013 CU3 / Office Web Apps Server 2013
OS: Windows Server 2012 R2
After implementing Office Web Apps server per the Integration with Exchange 2013 instructions, attachment previews in OWA show up as blank windows. The pop up says Opening your mailbox, then goes blank. I have the WAC endpoint configured in Exchange,
I can access the discovery URL from the Exchange servers, and I am seeing event 142. Some forums say that these events should be in the CAS application logs. I am seeing mine in the Mailbox server app logs. Has anyone seen a similar issue.
I have also attempted to view the ULS logs on the Office Web Apps server, but I don't see anything that looks like a rendering request. But, I also don't know what that request would look like. The Exchange and Office Web Apps server are
in the same network with no firewall in between them The local firewalls have also been turned off, so any type of blockage should not be the issue.

I dont want to be happy too soon, but i think for me this did the trick:
from time to time, this event appeared in the application eventlog:
Source: MSExchange Certificate Deployment
Event ID: 2005
Task Category: General
Level: Warning
Keywords: Classic
Description:
Federation or Auth certificate not found: ED2C3E86EBE821AAC2C0DEA85CAB5787E2CAC5F3. Unable to find the certificate in the local or neighboring sites. Confirm that the certificate is available in your topology and if necessary, reset the certificate on the Federation
Trust to a valid certificate using Set-FederationTrust or Set-AuthConfig. The certificate may take time to propagate to the local or neighboring sites.
The solution was found here: http://community.spiceworks.com/topic/512374-missing-the-microsoft-exchange-server-auth-certificate
1. New-ExchangeCertificate -KeySize 2048 -PrivateKeyExportable $true -SubjectName "cn= Microsoft Exchange Server Auth Certificate" -DomainName "*.yourdomain.com" -FriendlyName "Microsoft Exchange Server Auth Certificate" -Services smtp
Do not accept to replace the SMTP certificate when prompted
2. Note the thumbprint of the new certificate. Let us assume it is 7A39541F8DF58D4821967DD8F899B27410F7C081
3. $a=get-date
4. Set-AuthConfig -NewCertificateThumbprint 7A39541F8DF58D4821967DD8F899B27410F7C081 –NewCertificateEffectiveDate $a
Accept to continue despite the fact that the certificate effective date is not 48 hours into the future
5. Set-AuthConfig –PublishCertificate
6. Make sure to remove any potential reference to the previous certificate (which might not exist anymore) by doing Set-AuthConfig -ClearPreviousCertificate
Maybe this helps some of you too.

Got errors when trying to open word document with Office Web App Server and customized WOPI host

I am configuring the Office Web App Server with our ASP.NET MVC WOPI host based on this example. https://code.msdn.microsoft.com/office/Building-an-Office-Web-f98650d6. While both the OWA server and WOPI server has been set up and I can use Excel and PowerPoint
app to open and edit xls and ppt file now, there are problems opening word documents no matter I enable or disable the editing function of OWA server.
When I open a word document while enabling editing I got this error:
If I disable editing I got this message:
I have tried several file so I thought it is not the files' problem. Also I didn't find any exception in the log of OWA server.

Hi Gary Jiang,
Thanks for posting in MSDN forum.
This forum is for developers discussing issues about
apps for Office.
Based on the description, it seems that you got an issue when you deploy the code sample. If I understood clearly, I suggest that you contact the author of the code sample from the "Q and A" tab.
Also if you have the question about WOPI, I suggest that you get more effective response from
Office
Protocols forum.

Exchange 2013 OWA published through TMG: Unable to preview documents with Office Web App server

We configured our Exchange 2013 servers to use Office Web App for document previews on OWA. Everything works fine internally, and externally also when we access OWA directly. But when from an outside network we open a OWA session through TMG and try to preview
a document, we get the error "Sorry we cannot open this document, an error occured . . ."
Did anyone experience such an issue ?
Thanks,
Antonio

Hello,
Since directing accessing OWA from CAS is fine and the issue only occur when involving TMG, I think the issue is more related to TMG settings. Please find more efficient support

Office Web Apps Server , Excel Web Apps , Error , Event ID 5226

There is an environment of install Office Web Apps 2013 for SharePoint 2013 – with PDF Preview.
Having been able to use it without any problems.
One day, a preview of the Excel does not work properly.
Error or do not know the contents of the following, a solution to solve this issue anyone?
ERROR,
2014/XX/XX XX:55:30,
Excel Web App,5226,
Unable to create or access workbook cache at
C:\ProgramData\Microsoft\OfficeWebApps\Working\waccache\XXXX\Images.
Excel Services Application is unable to function without a workbook cache.

If you have not followed instructions according to the following article. You need to reconfigure office web apps for sharepoint
http://technet.microsoft.com/en-us/library/jj966220(v=office.15).aspx
"Applying Office Web Apps Server updates by using the automatic updates process isn’t supported with Office Web Apps Server. This is because updates to an Office Web Apps Server must be applied in a specific way, as described in this article"

How can i check the office web app server(wac client) is calling custom WOPI host?

I am getting an error when I testing my wopi host(which is the same as
example) with Office Web app server "Sorry, there was a problem and we can't open this document. If this happens again, try opening the document in Microsoft Word."
1-how can find the log files of this error?
2-how can i check the office web app server(wac client) is calling my WOPI host?
I am not sure about cumunication between owa to wopi host. I actually dont know how to implement checkfile and getfile functions to wopi host for waiting for call back from owa client.
Note:I am sure that office web app server is configured true. Because i test it with sharepoint 2013 and editing and viewing is working well.

Hi,
According to your post, my understanding is that
CheckFileInfo is how the WOPI application gets information about the file and the permissions a user has on the file. It should have a URL that looks like this:
HTTP://server/<...>/wopi*/files/<id>?access_token=<token>
While CheckFileInfo provides information about a file, GetFile returns the file itself. It should have a URL that looks like this:
HTTP://server/<...>/wopi*/files/<id>/contents?access_token=<token>
There is a great article for your reference.
http://blogs.msdn.com/b/officedevdocs/archive/2013/03/20/introducing-wopi.aspx
You can also refer to the following article which is about building an Office Web Apps(OWA) WOPI Host.

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).

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.

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

Will Office Web Apps Server 2013 work with SharePoint 2013 sites hosted in SP2010 compatibility mode?

We are planning a upgrade of a SP2010 farm to 2013. There has been a bit of customization so we wish to run the old sites on the new SP2013 platform in SP2010 compatibility mode.
So my question is will Office Web Apps Server 2013 work with the old sites hosted in compatibility mode?
I found a similar query from March 2014 found here
http://sharepoint.stackexchange.com/questions/93101/office-web-apps-2010-running-on-sharepoint-2013-for-compatibility-mode-sites/116281#116281
Has there been an update released to resolve this
Cheers D

Hi ,
According to your description, my understanding is that you need to know whether Office Web Apps 2013 is working with SharePoint 2013 sites which is in SharePoint 2010 compatibility mode.
For my test, Office Web Apps 2013 with SharePoint 2013 sites which is in SharePoint 2010 compatibility mode is working fine.

Office Web Apps Server 2013 - Word Web App - Problem with Tab space

Hello We have Office Web Apps Server 2013 running with SharePoint 2013. Users Editing a Word document with Office Web Apps, can't use "Tabs", any Word document with Tabs; the tabs are replaced with a single space.

Yes, currently the Word Web App does not support

SharePoint 2013 Anonymous (public) site and Office Web Apps Server 2013 issue with download.aspx

Our organization has a public facing anonymous site in SharePoint 2013 which allows access to documents (docx) in a library. ViewFormsLockdown is activated as we present the documents via CQWP / custom template. We are combating the usual
issue of multiple login prompts when using Internet Explorer when a user accesses said document. We also have tried using the Word Viewer (view only mode) from Office Web Apps Server 2013 which works well, but ...
the problem stems from the fact that users can go the file menu from the word view and choose to download the document (which is what we want), unfortunately it looks like the link redirects via /_layouts/15/download.aspx which also presents a login
prompt. Much has been written out there about doing direct links for documents via /_layouts/download.aspx to address multiple login prompts when the document is opening in word (from IE).
I've tried nearly every combination of recommendations (disabling client integration, browser file handling (permissive/strict), ViewFormsLockdown feature, web.config modifications with options and propfind verbs and more) all to varying levels of success,
but never totally getting rid of the prompt. It has been stated that because the downloads.aspx inherits from Microsoft.SharePoint.ApplicationPages.Download this will not allow anonymous access. We really want to use the word view from the Office
web app and have the file download functionality work from the menu there ... can anyone suggest an alternate fix? I might be wishing but will appreciate any guidance offered ...
cheers,
Dean

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:
<?xml version="1.0" encoding="utf-16"?>
<HealthReport xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

</HealthReport>
Reading some posts, it's a known issue fixable by adding HTTP-Activation feature... in Windows 2012. I have a Windows 2008 and .NET Framework 4.5 is installed. I've tried to add HTTP-Activation feature from .NET Framework 3.5, but a number
of format errors appear. I don't know how I could fix it in Windows 2008.
In addition, as I'm making test for share PPT and they aren't finally showed, this error appears also:

It seems that PPTs are being queued as they aren't actually showed.
Does this give you any clue?
Thank you very much.

Office Web App Server 2013: cannot edit word document with own WOPI Server

Hi all,
I tried to build our own WOPI Server to connect to Office Web App Server 2013 SP1. Viewing documents
in IE was possible quite easy to achieve. Now it comes to editing.
When I try to edit a document, I got a german message “Sie verfügen leider nicht über die Berechtigung zum Bearbeiten dieses Dokuments“.
This means something like „Sorry, you do not have any permission to modify this document”.
I enabled editing on the OWAS-Server while setup procedure
(Until now, I only have an InternalUrl but no ExternalUrl.)
PS C:\ > New-OfficeWebAppsFarm –InternalUrl “https://win-owas...”
–CertificateName "win-owas…" –EditingEnabled
ULS log shows
BaseDocument says editing is not supported [WebEditingEnabled: True] [SupportsEditing: True] [PinnedUsersRights: Read]
So far, I implemented these three REST service methods:
[OperationContract]
[WebInvoke
"GET":"api/wopi/files/{name}?access_token={access_token}"
"GET":"api/wopi/files/{name}/contents?access_token={access_token}"
"POST":"api/wopi/files/{name}/contents?access_token={access_token}"
Office Web App Server was downloaded from “Microsoft Volume Licensing Center”. I installed latest updates from Microsoft.
Did anybody succeed in writing to own WOPI an can give me some hints?
Thank you in advance.

Hi,
The discovery xml contains many lines. The one for editing docx is:
<action
name="edit"
urlsrc="https://win-owas.cado.camos.de/we/wordeditorframe.aspx?"<ui=UI_LLCC=""&><rs=DC_LLCC=""&><showpagestats=PERFSTATS=""&>"
ext="docx" requires="locks,cobalt,update"/>
I am calling it this way:
<iframe
src="https://win-owas.cado.camos.de/we/wordeditorframe.aspx?WOPISrc=http%3a%2f%2fpc-ms.cado.camos.de%3a8000%2fWOPI%2fapi%2Fwopi%2Ffiles%2FAbout_Keyboard_Input.docx&access_token=5268690b-19c6-496d-8ae6-b694f8e7bd0c"
I’m not sure whether or not I implemented "locks,cobalt,update" correct, but I do not see any ‘edit-’network traffic from OWAS-Server to WOPI-Server. So I cannot debug anything. I will (re)check the articles you mentioned.
Thank you for your help.
