Microsoft is testing out new icons for its most popular apps. A recent survey inspired an artist to make a modernized Outlook logo in the app's clasic yellow.

The bold yellow "Ad" icon that started showing up in Google search results on smartphones in September, now appear to be getting a test run in the UK.

That would be a return to form since the Outlook icon was changed from yellow to blue over a decade ago. As far as I can tell, the new yellow Outlook icon is only a fan creation by Thunder_Ruler0.
