If you work as an Office 365 IT administrator, then the official Office 365 Admin app from Microsoft should be on your quick list of apps for Windows Phone. The app lets you "manage your users including resetting their passwords. In addition, you can also read the latest messages from Message Center, the central location for Office 365 service communications and view any active service support requests."
Today, the Office 365 Admin app is getting bumped to version 2.0. The last time we mentioned the app was back in November 2013, so this update is a welcomed one. Did someone say makeover?
