New Feature Requests: External Sharing Controls for Office 365 Groups

[Adam Parker]

I would like to request the following external sharing controls for Office 365 groups:

• Per Group Sharing Controls in order to limit the ability to invite external users to those in a specified security group. (Described here: OneDrive Blog)
  
• Ability to disable external sharing by default for newly created Office 365 Groups. Currently if external sharing is enabled at the tenant level, new Office 365 Groups also have external sharing enabled by default. If an organization only wants to allow external sharing for a limited number of Office 365 Groups, but still allow any user to create a new Office 365 Group, IT is required to manually disable external sharing on every new group that is created which is not feasible.
  
  

Thanks,

Adam

Are you aware of this:
- Allow / Block Guest Access to Groups: https://technet.microsoft.com/en-us/library/mt842200(v=exchg.150).aspx (It involves working with PowerShell)

Well, remember that the Group model is "equal rights" for all members. Plus, such feature will tie the Group membership to another (security) Group.

The controls we have around Guest user support are already per-Group, you just need to create the relevant settings object and assign it to the Group. If you edit the Global settings object, said settings will apply to newly created Groups as well. If you want to configure settings that are specific to the Group site however, you will have to do it manually post-creation.
