2014 - Google created Hangouts video chat plug-in for Outlook to challenge Amazon Chime

Some Google Apps users instead of native email solution - GMail are using desktop version of MS Outlook. And so far they didn't have the ability to chat and make video calls (like GMail users). Of course, there is an integration of Outlook and Microsoft Lync, but companies that are using Google Apps hardly deploy Microsoft Lync. So Google decided to fix this problem and released Google Hangouts plugin for MS Outlook. It allows to easily make video calls to Outlook contacts, organize group videoconefernce calls with up to 10 people and schedule video meetings in Outlook's Calendar. Recall recently Microsoft rolled out Skype integration for, but it works only with the online version of Outlook.
