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
via our TMG forum:

Open Documents with Office Web App - SharePoint 2013

We have configured Office Web App for our SharePoint 2013 Farm and in Site settings, Site Collection Features, have disabled "Open Documents in Client Applications by Default" . Out of 15 sites, all documents in 13 sites open in Office
Web App. One of the 2 sites where the document still open using Client Application is a Wiki site.
Advanced propertied for the libraries settings has been set to "Use the server default (Open in the browser)". Anything else to check to open documents in Office Web App?
Thanks

Hi,
As I understand, you encountered the issue when you want to open documents with Office Web App.
Check things below:
1. In the library setting->advanced setting, you can choose the open in the browser to see if the same situation will occur.
2. Check if you have not enable the Open Documents in Client Applications by Default feature.
If you choose Activate to enable the Open in Client feature (documents will open in the client application), or
Deactivate to disable the Open in Client feature (documents will open in the browser).
You can go to Site setting->site collection administration->site collection feature->Open
Documents in Client Applications by Default to set the feature.
The article below is about how to set the default open behavior for browser-enabled documents.

Got a lab environment to test Office Web App Server integration with Exchange 2013
i have followed the instructions given here

http://technet.microsoft.com/library/2591b1be-92c4-4192-9f5e-e4e6b319170a
After all required configuration , i am still unable to preview the office documents from OWA
Receiving the following messages by clicking on the Preview link next to the attachment:
Word Document : "Sorry, there was a problem and we can't open this document. If this happens again, try opening the document in Microsoft Word."
Excel Document: "We couldn't find the file you wanted. It's possible the file was renamed, moved or deleted"
PowerPoint: "Sorry, we ran into a problem. Please try again"
As suggested i even see the Application Log the 140 and 142 Event IDs for MSExchange OWA
Already configured to enable the rendering of attachments through OWAS both on public and private computers:
This is what I can see in the ULS log on the Web App Server

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.

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.
Has anyone noticed this? Is this a bug?
-thanks
thomas
-Tom

Yes, currently the Word Web App does not support
Tab Keyboard shortcut for editing document content .
For more information, you can have a look at
the article:

Using Office Web Apps Server 2013 without SharePoint, Lync, or Exchange

I'm trying to use the Office Web Apps Server 2013 as an online viewer of Office documents (using the Online Viewer). I've set up a New-OfficeWebAppsFarm with editing disabled, no UNC paths, and an external URL with SSL Offloaded to my Load balancer.
I don't want to use it with SharePoint, Lync or Exchange. Just use it to view documents online (similar to Google Docs Viewer).
However, when I point the Office Web Apps Server to a remote file online (e.x. a DOC hosted on a website), I get an error opening it.
I've checked the health statuses of my OWA Servers, and it says Healthy.
When I check the Event viewer of my OWA Server, I see 501 WOPI errors:
Could not contact WOPI End Point. Error details - 'NotImplemented url - https://sample-owa-url.com/oh/wopi/files/@/wFileId?wFileId=http%3A%2F%2Fwww%2Eimr%2Esandia%2Egov%2Fimrtemplate%2Edoc&access_token=1&access_token_ttl=0'.
It seems OWA is trying to connect to the path /oh/wopi/files.... but the server is responding NotImplemented.
What do I have to get this to work?
Thanks for any help!

Did you ever find an answer? I have the exact same Issue.
I have 2 WAC servers behind a load balancer with SSL offloaded to the LB. Both servers report healthy with Get-OfficeWebAppsMachine
Works fine with SharePoint 2013.
When I use it with a remote file, served using HTTP with no authentication (anonymous), I get a generic "Sorry there was a problem and we can't open this document..." error.
In the ULS and event viewer, I see the WOPI error and 501 which basically says:
Could not contact WOPI End Point. Error details - 'NotImplemented url - https://sample-owa-url.com/oh/wopi/files/@/wFileId?wFileId=http%3A%2F%2Fwww%2Blah%2Ecom%2FWordDocument%2Edocx&access_token=1&access_token_ttl=0'.
I also sometimes see this:
<HealthMessage>WordViewerWfeWatchdog reported status for WebWordViewer in category 'WfeRedirect'. Reported status: /default.aspx returned a 404, which means that we didn't have where to redirect.</HealthMessage>
The very interesting part s that I have a dev server, with OWA (WAC) installed, thats not going through a LB and does not use SSL, that works just fine with the same public url word document.

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
SharePoint 2013 - Setup, Upgrade, Administration and Operations .

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.
Regards
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 Server 2013 patching and reported build numbers

Sorry ahead of time for asking this on a Sharepoint forum, but I can't find OWAS forums anywhere.
When applying patches to Office Web Apps Server the build version as reported by Control Panel | Program and Features does not change. RTM build number is 15.0.4420.1017. KB2760445 moves version to 15.0.4481.1005. You can install it but
the version/build number as reported by control panel will not change. I can't find information on build versions on MS website. I am using Roger Haueter blog
here to help me with that. I tries manually downloading updates and applying them as well as relying on WSUS and MS Update. Results are the same. You can see the updates under "installed updates".
Please, share you knowledge.

This is normal. See these sites for how to identify the build number of the farm:

Office web apps server 2013 - launching search on loading page

Hello!
I use Office Web Apps Server 2013 for viewing documents on internal portal (it is not SharePoint, and documents is read only) with automatic generating links. Links are generated according instruction
on http://<OWA host>/op/generate.aspx (for example, http://<OWA host>/op/view.aspx?src=<path to file>).
I have some questions:
1) In some cases, when a document is openedI want
immediately start the search with some terms.
Can I give terms
to search in url params in generated url? For example, http://<OWA host>/op/view.aspx?src=<path to file>#search=<terms>?
Is there any other
way to run a search on page load?
2) I want to use multi-term search (when my search query is 'tame tamed taming', and
all individual words ('tame', 'tamed', 'taming')
are highlighted in document).
Is there a way to do it?
3)I want to use whole-word search (when my search query is'act', and words 'practice' or 'action' are not
highlighted in document).
Is there a way to do it?

Hi Jazzy.em
Thanks for posting in MSDN forum.
This forum is for developers discussing developing issues about
apps for Office. Since the issue is more about Office web app, I suggest that you get more effective response from
Office 365 forum.
The reason why we recommend posting appropriately is you will get the most qualified pool of respondents, and other partners who read the forums regularly can either share their knowledge or learn from your interaction with us.
Thanks for your understanding.

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 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.
