Microsoft Outlook is the official app for the popular Microsoft email client for Android that'll let you easily and comfortably manage your email accounts.
Like most apps of this kind, Microsoft Outlook includes pop-up notifications every time you receive an email (although this feature can be deactivated), calendar and contact synchronization, and folder viewing and synching. In fact, you can use your folders to easily filter all incoming mail.
Apart from all this, Microsoft Outlook lets you sync several email accounts on your Android device and keep them all active at the same time. Of course, when it comes to writing emails, you can choose between the different accounts, attach files, and do all the other things you can do on the desktop version of the program.
Microsoft Outlook is quite a useful email management tool that will prove to be really easy-to-use for those who use the desktop version. It is, in short, a (more or less) interesting alternative to the undisputed king of email clients on Android: Gmail.
