Recommendations on Naming Conventions for O365 Groups

We disabled group creation in AAD and made it so that our admin team can create groups on request (this is how our organization currently does all requests for SP sites, email groups, etc, so it made sense). This is to prevent the kind of chaos that you are referring to, ensure we dont have unnecessary duplication, and have some kind of structure. We are only on at the beginning of the process, but we did get out ahead of it before it could run rampid.

And I know, blah blah, empowering end users and shadow IT and all those buzz words, but my biggest complaint against Groups has always been provisioning so much garbage that isnt needed, it makes a massive mess of things for IT.

Someone else mentioned in another thread, it would be potentially a good practice to do some PowerShell scripting and to do something like this: get all groups, if it doesnt have GRP- on the front, add it, otherwise skip:

$O365Groups = Get-UnifiedGroup
foreach ($O365Group in $O365Groups){
Write-Host $O365Group.DisplayName
if($O365Group.DisplayName -like "GRP-*"){
Write-Host "OK" -ForegroundColor Green
} else {
Write-Host "Not OK" -ForegroundColor Red
Set-UnifiedGroup -Identity $O365Group.Name -DisplayName ("GRP-"+($O365Group.DisplayName))
}
}
