In a post to Office Blogs on September 8, 2016, the Office Team announced a new guest access feature for Office 365 Groups—the group membership service, which provides a single identity for teams in Office 365. Features that are being enabled include:
- Guest user access to Office 365 Group conversations
- Guest user access to files in document libraries
- Guest user access to the Office 365 Group calendar
- Guest user access to an Office 365 Group's Notebook (OneNote)
As the post says, the functionality is rolling out in phases, and you can expect to hear much more about Microsoft's expanding collaboration story for Office 365 Groups at the Ignite conference in September 2016.

If you want to know in more detail how external guest user accounts works, including the restrictions, what guest users have access to and what they don't as this feature rolls out, and how to control it, we also recommend a great article published on our sister site, Petri IT Knowledgebase by Exchange MVP Tony Redmond called External Access for Office 365 Groups. If your team uses Office 365 Groups, both resources are worth your time to read.
