In 2018 Microsoft released the Diagnostic Data Viewer (DDV) which is a tool that lets you review the raw diagnostic data Windows is sending to Microsoft. Now you can also view Office diagnostic data using the same viewer. The DDV requires Windows 10, version 1803 or newer. Viewing diagnostic data from Office requires Office 365, or Office 2019, for Windows, version 1904 or newer.
Not sure which version of Windows or Office you're running?
How it works
The Diagnostic Data Viewer (DDV) has been able to show you the Windows diagnostic data, and starting with Office version 1904 we've now enabled it to show you Office diagnostic data as well. We'll get into the details in a moment, but basically what you do is start the DDV in Windows, then go to any compatible Office desktop application - such as Word, Excel, or PowerPoint - and turn on diagnostic data viewing. When you return to the DDV you'll see Office diagnostic data in addition to the Windows diagnostic data.
First you'll need to download and install the Diagnostic Data Viewer, if you haven't already. See Diagnostic Data Viewer Overview for more details on that process.
Once you are done installing, start the Diagnostic Data Viewer on your Windows machine.
Launch the Diagnostic Data Viewer from the Start menu.
In the Diagnostic Data Viewer, go to Settings and ensure that Office diagnostic data viewing is toggled on.
Note: If you don't see the option to turn on Office diagnostic data viewing you may have an older version of the DDV. Office diagnostic data viewing requires DDV version 3 or newer. Your DDV should update automatically, but if for some reason it hasn't, you can click here to go to the Microsoft Store and manually check for updates.
Viewing Office data
With the Diagnostic Data Viewer running:
Open any Office desktop app, such as Word or Excel.
Go to File > Options > Trust Center > Trust Center Settings > Privacy Options.
Select the Diagnostic Data Viewer button.
Choose Enable data viewing on this machine and select OK.
Switch back over to the Diagnostic Data Viewer and within a few minutes you should start seeing diagnostic data from Office. You only need to turn diagnostic data viewing on (or off) in one application. That turns diagnostic data viewing on (or off) for all supported Office applications on this machine at the same time.
The DDV connection will expire after 24 hours. If you want to continue viewing diagnostic data beyond 24 hours simply re-enable data viewing in Office with the steps above.
If you're trying to view diagnostic data on your machine and you get an error that "DDV is not running", even though it is, restart your machine and try again.
You won't be able to view diagnostic data on the local machine if you've launched Office from the start menu, or a command prompt, with "Run as Administrator".
If any diagnostic data is generated at the very end of a session, Office will cache that data and upload it at the start of the next session. That means in some instances you may see data from the end of the previous session appear at the start of a new session. It also means that you may not see the very last bits of data from a session until you restart the app to launch a new session.
