Introducing guest access for Office 365 Groups!
Thanks Jaroslav Karlik for reaching out!
1. For external users to access resources, the user has to first redeem itself, which users can do through the View Files link in Welcome email, they will be redirected to the sign-up/sign-in page. Gmail users can create an Microsoft account through this sign-up process with login id as exactly same as their gmail-id, for e.g. bob@gmail.com can have Microsoft account as bob@gmail.com and use its Microsoft account credentials to login. This account can be used by Gmail user to access any shared resource with him in that tenant.
2. Guest access for planner is in the road-map.
By the way, the process to redeem an invitation (to essentially validate the guest user object created in AAD) is described in https://www.petri.com/external-access-office-365-groups. Just saying.
