What happened to the option to connect to a new M365 Group? This was part of our provisioning process. Create, the classic team site, make changes to the permission levels, connect the M365 Group, then create the Teams Team.

Does this have to be done programmatically now?

If you are using a classic team site template, then this should still be possible via the UI: https://docs.microsoft.com/en-us/sharepoint/dev/transform/modernize-connect-to-office365-group#connect-a-microsoft-365-group-using-the-sharepoint-user-interface

You can raise a bug with Microsoft via the Microsoft 365 admin portal if you are unable to do so.


From your screenshot, the template for your site is "Team site (no Office 365 group)", which is a modern view site without office 365 group by default.

However, "Connect to New Microsoft 365 group" UI option only applies to classic templates like the classic team site template (STS#0) and community site template (COMMUNITY#0), and your team site template is "STS#3",so the button missed.

Difference between STS#0 and STS#3:

To find the site template via viewing the source of the start page (Ctrl + U) and search for JavaScript variable:


As a workaround, we suggest you use powershell to connect the site to a new Microsoft 365 group:

$UserName = "[email protected]"   
$SPOAdminCenterUrl = "https://tenant-admin.sharepoint.com"   
$ClassicSPOSite = "https://tenant.sharepoint.com/sites/ClassicSPOSite/"   
$O365Cred = Get-Credential -UserName $UserName  
Connect-SPOService -Url $SPOAdminCenterUrl -Credential $O365Cred   
$GroupDisplayName="<Group Display Name>"   
Set-SPOSiteOffice365Group -Site $ClassicSPOSite -DisplayName $GroupDisplayName -Alias $GroupAlias -IsPublic $true

  • The question states that he created a classic team site, not a modern site. Dec 7, 2020 at 9:14
  • Yes, it's the classic site with modern view.

You can still connect the Group, but for some reason, the link has been removed when on the Home page. If you navigate to Site Information => View All Site Settings, the link is available:

It may be a bug as @Callum stated, but at least there's a workaround.
