Actually have couple of points regarding this "Invite others" feature.
- One of our users tried to invite external user (outside of our O365) with "Invite Others" button but apparently that invitation link only works within our O365 subscirption. Why have two different options to share the Group with others - "Add members" and "Invite others"? It is very confusing and especially when the latter only works to invite users in the same tenant.
- Also, I started looking deeper to this, because this "Invite others" is a new feature, and noticed that "Invite others" button is actually missing in some of my Groups. What is the logic here?
Private group, I'm owner: "Invite others" button is present
Private group with guests, I'm owner: "Invite others" button is missing
Private group, I'm member: "Invite others" button is missing
Before opening a support case with MS I thought I would ask here..
