If you're a Windows Insider on the Fast Ring, then you may have spotted something new in the Outlook Mobile and Calendar today. Indeed, Microsoft released a new app update yesterday which brought new contact icons that show up next to all your emails. These new icons are similar to those found on the Windows 10 Contacts app, except that they bring a nice touch of colour to the Outlook Mobile app. For contacts that already have a profile picture, you'll see it in the contact icon instead of the white initials.
Microsoft didn't release a changelog for the update, though we guess that it also includes some bug fixes and improvements. As usual, we except this new version to be rolled out to non-Insiders in the coming weeks, let us know in the comments if you spot other new features
