Office 365 – Office 365 Pro is changing the default search engine

Coming with the version 2002 of Office 365 Pro Plus, a browser extension is going to be installed on Chrome to make Bing the default search engine.

This change is scheduled to be deployed starting February 2020 for the Targeted channel, March 2010 for the Monthly channel and with the next release for Semi-Annual channel.

Update channel Version Release date
Monthly Channel (Targeted) Version 2002 Middle of February 2020
Monthly Version 2002 Early March 2020
Semi-Annual (Targeted) To be determined March 10, 2020
Semi-Annual To be determined July 14, 2020

There is plan to do the same for FireFox.

This change,so far, only applies to certain locations:

  • Australia
  • Canada
  • France
  • Germany
  • India
  • UK
  • US

New and updated installation will get this extension; unless Bing is already set as the default search engine in Chrome (which is quite unlikely Smile)

Your end-users will be able to disable the extension as any Chrome extension. The extension will need to be disabled if your end-users wants to change back the default search engine; using the usual search engine setting in the browser will not work.


As administrator, you can control if the extension can be installed or not using Group Policy, the Office Deployment Tool (for new installation), SCCM or Intune.
