O365 groups missing - SharePoint Modern Team Site

Occasional Contributor

Hello Everyone,

We have over 450+ team site in our SPO tenant and we started to noticed that most of these site does not have an O365 group associated/attached to it. Looks like O365 groups did not get created during the site creation.

>  The built in filter view in SPO admin page- active sites - shows that all the sites has O365 groups 
however cannot find them under groups in any admin page (SPO,Exchange groups, or in AzurePortal)

> Tried to create a new group via PS and i get this message
Connect-SPOService -Url $SPOAdminCenterUrl -Credential $O365Cred

$GroupDisplayName="Group Display Name"
$GroupAlias="GroupAlias"
Set-SPOSiteOffice365Group -Site $ModernSPOSite -DisplayName $GroupDisplayName -Alias $GroupAlias
====
Output
====
Set-SPOSiteOffice365Group : This site already has an O365 Group attached.

Any suggestion on how to get a report or list of all the site which does not have O365 groups associated to the Modern site

 

Thanks in advanced.

You can actually create a modern SP team site without a office 365 group, but that doesn’t seem to be applicable here since it says it belongs to a group?
Have you tried to search for office 365 groups in the office 365 admin portal - groups?
Powershell: get-unifiedgroup with the exchange ps module connected!

How did the sites get created? Via SP?

@adam deltinger  The site was creating via SP 
these deleted groups are not listed under O365 admin portal- groups, nor in the azure portal under deleted groups. Will try this Powershell: get-unifiedgroup with the exchange ps module connected! and let you know. 
Thanks for your time :)
