Public, Non-public and Org-wide groups
In Microsoft Groups there are three kinds of staff, Public and Non-public and Org-wide.
Public means anybody within the organisation (tenant) can be part of the staff at any time with none approval
Non-public means house owners of the staff should admit new members.
Org-wide, which is a particular sort of staff that mechanically provides everybody within the organisation group to be part of a single staff for collaboration. You can also make a couple of Org-wide staff do you have to wish to. Solely International admins can create an org-wide staff through the use of the Groups consumer. That is as much as 10,000 members on the time of writing. Word: org-wide groups aren’t but out there for Groups for Training.
I’m not in love with the private and non-private as these varieties don’t have any bearing as to there being exterior friends (from different organisations/tenants) within the staff. Open and Closed may make extra sense, however it’s what it’s.
When creating them you get to decide on
When you select “From scratch”, you may then select your sort

Just lately Microsoft modified this, now the choice doesn’t present at creation or beneath the “edit team” choices. Non-public groups are all the time hidden from the listing and public groups are all the time proven. All documentation associated to discoverability has been eliminated (for instance this hyperlink from the TAC now redirects to the generic documentation (right here)
Now all non-public groups are hidden from search and the listing, no matter their earlier discoverability state.
Make sure you subscribe to the weblog for updates on this as I get additional data.
In 2018, Microsoft thought of going the opposite means with this, making all non-public groups discoverable, however later modified their thoughts. I feel making all of them discoverable would have undoubtedly been a mistake,
The PowerShell parameter nonetheless exists, however I count on can be depreciated.
There may be additionally one other “visibility” possibility that may be set for those who create groups from Microsoft Graph API, “Hiddenmembership”. That is completely different from discoverability however can also be legacy.
This appears to be retired/unused, you may test if in case you have any through PowerShell
