Outlook products

While this email application comes with Microsoft Office 365, users can still get an Outlook account by signing up on their website. You'll get 15GB worth of email storage space the same as any other email service provider on the web. If you download the Outlook app, you can get a whopping 50 GB worth of storage great for sending and receiving emails with large file attachments.

Apart from the email suite, Outlook also comes with Microsoft's Calendar application to help you easily schedule meetings and appointments. This application notifies you ahead of your sessions so that you are in the loop, always. Outlook also helps you manage contacts using the People application.

Where can you run this program?

This email suite also offers apps supported by both Android and iOS devices so that you can manage your inbox on the go using your smartphone or your iPad. Finally, this popular Microsoft program can be downloaded on Windows Mobile or integrated into numerous business systems and applications, including Skype, Evernote, Paypal, Yelp, and many more. Truly ideal for any type of user.

Is there a better alternative?

Microsoft Outlook 365

There are plenty of alternative global communications software to Outlook. If you need to use an email suite mostly for personal use, Google's Gmail is a good choice. It's free and can be accessed through any web browser or its app on Android and iOS. It also offers the same amount of storage as that of the free Outlook account, allowing messages with up to 50 MB of file attachments.

For company and business use, Workplace by Facebook is another effective communication tool that gives a more instant experience. It's a somewhat spitting image of the social media website, except for the fact that it's a central communication hub for staff and managers to use in their day-to-day work.

Our take

From the looks of it, Outlook is definitely worth giving a shot. The best features include classifying emails by folders and tags, as well as sorting out email through file size. Speed and performance will not be a problem for those using the desktop version, and the interface is clear and easy to understand.

So, if you're a fan of keeping your inbox organized and personalized, then Outlook is the tool for you.
