I am trying to allow internal users to share files from their office 365 groups externally. They receive the error "Administrative policies don't allow sharing with people outside your organization."

 

I have checked all the settings and everything points to a user's ability to share externally. There are some sharepoint online site collections with less sharing permissions and office 365 groups cannot invite guest users.

 

My question is, how do I enable external sharing as the default for all office 365 groups? Can I enable sharing externally without enabling guest access?

 

I realise I can enable external sharing without guest access, by powershell script (-SharingCapability ExternalUserSharingOnly), but in this world of office 365 groups popping up everywhere I don't have the time to do this manually for every group!

Well they just recently announced changes in the external sharing model for Groups. Until that happens though, your only option is to change the setting on per-group basis via PowerShell.
