"Everyone except external users" switch from Visitors to Members on PUBLIC O365 Group sites
Anyone having the following issue? For most O365 Public Group SharePoint sites, I set "Everyone except external users" as visitors and not members (who can delete everything in the site!!) . ...
Elizabeth Robinson On my side, there was no change in group membership (and the group was not used with yammer) but this is an interesting observation.
Martin-Coupal as I understand it the Yammer group is essentially an O365 group but the membership change is definitely what's happening on my end. We have it escalated with MS support now so I'll update with the resolution in case it helps with what's happening on your end.
