Office Online Server Showing “Unhealthy” Status


*UPDATE*

The new version of Office Online Server released on 11/17/2016 has health fixes in place.

You may still get a OneNoteMerge health error in the event log like this:

<?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”>
<HealthMessage>WebOneNoteWatchdog reported status for OneNoteMerge in category ‘Ping’. Reported status: OneNote Merge Ping test failed. OneNoteMerge.exe not available to execute merge</HealthMessage>
<Severity xsi:nil=”true” />
</HealthReport>

If you are then you will need to install the X64 version of the Visual Studio Runtime : https://www.microsoft.com/en-us/download/details.aspx?id=40784

 

 

Problem:

Office Online Server (OOS) shows that the servers are in a Unhealthy status. This status will even occur on a new farm with default settings.

Unhealthy

Cause:

The OOS product team has identified a few different health checks that are failing and causing the status message to show unhealthy.

Solution:

The OOS product team is in the process of correcting the health checks in an upcoming patch for OOS. We do not have a timeline on when this will be released, but this blog will be updated when the patch is available.

 

*The healthStatus message should not be a indication of functionality of a OOS farm.

    01. cd %SYSTEMROOT%\System32\wben
    02. regsvr32.exe WmiApRpl.dlll

    Any tentative date when the fix will be available for this issue?

  3. scks says:

    Sorry, didn’t notice the update.
    We have to uninstall the previous version of office online server and then install November 2016 released version to resolve this health issue? are there any kind of updates released that can be used to fix the issue without uninstalling current version?

    Install Visual C++ Redistributable for Visual Studio 2013 both 32 bit and 64 bit after that wait for 15 minutes, health status would turn to HEALTHY.

  8. I Installed OOS November 2016 release but still getting the Unhealthy Status, I installed Visual C++ Redistributable for Visual Studio 2013 both 32 bit and 64 bit but no luck. here is one of th error…UlsControllerWatchdog reported status for UlsController in category ‘Verify Trace Logging’. Reported status: Trace string is found but the format is not correct in C:\ProgramData\Microsoft\OfficeWebApps\Data\Logs\ULS.

    1. This is one of the errors that should have been addressed with the November release. You uninstalled the previous version and used the new installer from the November release correct?

      I cannot say for sure, but can you verify your Regional settings. We have a OOS Farm deployed and it was also in an Unhealthy state. One of the event log errors was also “…but the format is not correct..”. I did set both OOS Servers Regional settings – Formats to match English US + the language for non-Unicode programs set English US. I also did run the copy current settings to Welcome screen and system accounts in the Administrative section. I did reboot both machines and they very Healhty afterwards. It’s just my assumption that the Regional settings are related, but I cannot say for sure.

      Its known issue even it though the status is unhealthy you will still be able to share the PPT https://blogs.technet.microsoft.com/office_web_apps_server_2013_support_blog/2016/10/26/oos-unhealthy/

  9. Gustav says:

    We have installed the new Version of Online Server 2016 and get this error: The following fields has the wrong format or content: [ Timestamp ]. Because of that the status is unhealthy, but the OOS works without any problems.
    Is it necesserary to install the language Pack?
