Microsoft has announced that users of the new Outlook.com experience will soon have improved support for handling files from Google Drive and photos from Facebook. The updates are going to be rolling out over the course of the next few weeks and it is a back end change so there is nothing you need to do. Once you have the update, Google Drive files will be available to you from the Attach menu when creating an email. Today when you want to do this you have to open a wholly separate tab. That will no longer be the case and it will make attaching files out of Google Drive quicker and simpler.
Microsoft today sent an email to all Outlook.com customers that Facebook Messenger and Google Chat integration with the web-based email service is no longer available. The email outlines that in the next couple of weeks that users will no longer be able to have instant message sessions from Outlook.com to these other services. While no specifics are given on why Facebook Messenger integration is going away, Microsoft was quite clear that the reason Google Chat integration is going away is due to a decision by Google to discontinue the chat protocol.
