Answer:

When configuring an Office 365 Group endpoint, you must enter the Office 365 Group site URL. ​​It will be in a format similar to the one highlighted below:

 

The URL to be used will be one of the following two formats:

• ​https://ptsdemolab.sharepoint.com/sites/marketinggroup/
  
• ​https://ptsdemolab.sharepoint.com/teams/marketinggroup/

           ​​NOTE: ​Exclude the "/Shared%20Documents/Forms/AllItems.aspx" part of the URL.

To quickly find the SharePoint site URL for all Office 365 groups for the tenant, execute the following remote PowerShell commands:

NOTE: The commands will need to be run as the global administrator of the target tenant.

$cred = Get-Credential​​​
$session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://ps.outlook.com/powershell/ -Credential $cred -Authentication Basic -AllowRedirection
Import-PSSession $session
Get-UnifiedGroup | fl Displayname,SharePointSiteUrl
​Remove-PSSession $session
