UPDATE 2/11/20:    
The Office 365 product team has changed direction.

“…we heard that customers don’t want Office 365 ProPlus to change search defaults without an opt-in, and they need a way to govern these changes on unmanaged devices.”

As a result, “the Microsoft Search in Bing extension will not ship with Version 2002 of Office 365 ProPlus.” 

Read the announcement for more details:

• Update to Microsoft Search in Bing through Office 365 ProPlus

UPDATE 1/30/20:
FYI: The version “2002” is in fact, correct, and not a typo.  It represents “Year 2020 & Month February (02)”. 

ORIGINAL POST:
Starting with Version 2002 of Office 365 ProPlus, an extension for Microsoft Search in Bing will be installed that makes Bing the default search engine for the Google Chrome web browser only on devices in a limited number of locations. This extension will be installed with new installations of Office 365 ProPlus or when existing installations of Office 365 ProPlus are updated.

If you don’t want the extension installed, follow these steps. Also, if Bing is already the default search engine, the extension doesn’t get installed.
