This is the second beta apps collection I would like to share after Google Beta Apps Collection
Microsoft has a huge list of Android apps and mostly all of them are available for beta testing. Besides that, Microsoft has a different beta management strategy and they use Google Plus communities a lot. As an additional plus - they update their changelogs frequently and you can always see what you are actually beta testing. Additionally, you can always identify a beta product by the "Preview" ⚡️prefix.

SwiftKey keyboard is a very popular keyboard which was one of the first swipe keyboards ⌨️. If I am not mistaken, it was bought by Microsoft in 2016 for 250k. It was one of the first Android apps bought by Microsoft. At this time it already had smart words predictions feature and a huge user base. From the beta testing perspective, SwiftKey app had a Google group for beta testers and good community management culture at that moment already. At some point, they released a standalone beta version of SwiftKey app. From this moment, Android users are able to install two SwiftKey apps (Stable and Beta) at the same time.
App description:
Welcome to the SwiftKey beta program - here you can test early performance updates, new unreleased features, customizations, and special themes. Thanks for helping us make SwiftKey the best it can be! The SwiftKey beta app for Android will not replace the regular SwiftKey app on your phone but will be downloaded as a second app so you can switch between the two for comparison.
Microsoft Launcher Beta (former Arrow Launcher)

Arrow launcher was originally developed by the team from Beijing in China. This team is also famous as a developer of the Next lock screen app. Not sure about details but they joined a Garage project from Microsoft in 2017. You can find more details on their Garage Profile. Arrow launcher was renamed to the Microsoft launcher and they started adding integration with Microsoft ecosystem after that. It brought features like Cortana integration, Onedrive sync and others to the app. Arrow launcher had a big beta testing community in Google+ since the beginning. This community is still working and growing. You can always find recent changelogs there and share your feedback.

LinkedIn Beta

LinkedIn was acquired by Microsoft in 2016. As far as I know, the beta release channel was opened later in 2017. This app just has a normal public beta in Google Play. Nothing special here.

HERE Maps Beta
Technically, this app shouldn't be a part of this list. This app was sold by Nokia in 2015 to the Automaker's consortium. At the same time, Microsoft had a deal with Here in order to be able to use Here maps data in their products. In addition, Here maps was an official maps provider for Windows phones. In fact, Here maps is a separate company and it is not a part of Microsoft. Windows phone is no longer supported and in the current Microsoft ecosystem for Android, Here Maps stays in the same maps provider spot.
