Microsoft has redesigned its Office icons five years since the last update. The new design reflects a more seamless and collaborative nature of Office 365.

For instance, the Excel icon has been redesigned into a rectangular shape to reflect the spreadsheets, while Powerpoint has a circular pie chart and Outlook has a mail envelope as its icon, Engadget reported.

The new icons will reach apps and the web in the coming months. It is to note that the change to the icons does not mean any functional improvements.
