How to limit telemetry transmission to Office 365

Office 365, like Microsoft Windows, Microsoft Office and other Microsoft products, collects and transmits telemetry data to Microsoft servers by default
How to limit telemetry transmission to Office 365

Most users have only a few options available to restrict data collection in Windows 10 and other Microsoft products. However, corporate users get more options for blocking telemetry.

Administrators can use an undocumented setting to limit the transmission of diagnostic data to Office 365.

For the first time, information about this parameter appeared on the twitter of Aleksandar Milenkoski. He analyzed the telemetry processing mechanism in the Office and sent his report to the German Federal Office for Information Security.

A computer networking specialist might require to lift and transfer heavy computer devices, travel or install networking cables or devices.


The report provides detailed information about telemetry in Office, and an entire chapter is devoted to disabling the transmission of diagnostic data. The researcher lists the Microsoft servers to which the diagnostic data is sent and reveals information about an undocumented registry setting that could restrict telemetry.

How to restrict telemetry transmission to Office 365. Using an undocumented parameter
To restrict telemetry transmission to Office 365, use Registry Editor:

Press the Windows+ keys  Rto open the Run command window.
Type  regedit and click OK to open Registry Editor. Confirm the User Account Control request.
Go to the following path:
HKEY_CURRENT_USER \ Software \ Policies \ Microsoft \ office \ common \ clienttelemetry \
clienttelemetry
Some sections may be missing by default. In this case, go to the last available section - in most cases this is the Microsoft section .
Right-click this section and select New> Section .
Give the section an appropriate name, for example office , and press Enter.
Repeat the procedure to create any missing partitions.
Right-click the clienttelemetry section and select New> DWORD (32-bit) Value .
Name the new parameter DisableTelemetry and press Enter.
Double click on the created parameter and change the value from 0 to 1 .
Click OK.
Reboot your computer.
Milenkoski notes:

Setting the DisableTelemetry registry value to 1 disables the Aria and Nexus Office telemetry modules. For example, if this registry key is added, Windows applications no longer load the MSOARIANEXT.dll library, which is responsible for the Aria module.

The researcher claims that adding this parameter does not affect the functionality of Office. Additionally, this setting does not completely disable telemetry in Office:
