Introducing guest access for Office 365 Groups!

What does your AAD policy for groups show when you look at the settings using 

Get-MsolAllSettings | ForEach Values?

You need:

• AllowToAddGuests is True, meaning that guest users are allowed for this tenant.
• AllowGueststoAccessGroups is True, meaning that guest users can access Office 365 Groups.

I have been using this feature for the last month or so with a lot of success. For instance, with a team of people from Microsoft and other companies to build the "Field Guide to Office 365 Groups" session for Ignite. The "flighting" of the feature to First Release tenants takes time as multiple components have to be in place for everything to work and when they all come together, you'll be able to use guest access as documented.

FWIW, I have an article coming on Petri.com today that describes my experience of using guest access and some of the twists along the way. You might get some value from that text. And of course, we will have an update for the Office 365 for IT Pros eBook that covers this topic in depth. I think we'll release an update for the PDF, EPUB, and Kindle versions of the book next Monday.
