Adding external contacts to Microsoft 365 groups within your organization can significantly enhance collaboration and productivity within your Office 365 environment. But manually verifying each Office 365 group to check for external contacts can be a time-consuming task, especially when dealing with multiple groups. Therefore, use the Get-MgContactMemberOf cmdlet to retrieve all groups of a specific contact in a short time. 

$groupId = (Get-MgContactMemberOf -OrgContactId <ContactId>).Id  
$group = Get-MgGroup -Filter "id eq '$groupId'"  
$groupName = (Get-MgGroup -Filter "id eq '$groupId'").DisplayName  
$contact = Get-MgContact -OrgContactId <ContactId> 
Write-Host "$($contact.DisplayName) belongs to group: $groupName" -ForegroundColor Green 

 

Check Whether a Contact is Member of Specific Groups

The Confirm-MgContactMemberGroup graph cmdlet can be used to confirm whether a contact is a member of a group.. This cmdlet allows you to check the group membership status of a particular contact.  

By executing the PowerShell script below, you can easily determine whether the contact is a member of the specified group or not. This functionality is useful for managing and organizing contacts within groups, enabling you to perform actions or apply settings based on their membership status. 

$ContactId = (Get-MgContact -Filter "displayName eq '<Contact’s Display Name>'").id    
$GroupIds = @("<Group ID 1>", "<Group ID 2>")    
foreach($GroupId in $GroupIds){    
    $IsMember = Confirm-MgContactMemberGroup -GroupIds $GroupId -OrgContactId $ContactId    
     if($IsMember){    
        $Group = Get-MgGroup -Filter "id eq '$GroupId'"  
        Write-Host "Contact $($Contact.displayName) is a member of group $($Group.displayName)" -ForegroundColor Green 
    } else {    
        $Group = Get-MgGroup -Filter "id eq '$GroupId'"  
        Write-Host "Contact $($Contact.displayName) is not a member of group $($Group.displayName)" -ForegroundColor Green 
    }

$contactName = (Get-MgContact -Filter "id eq '$orgContactId'").DisplayName 

$groupNames = (Get-MgContactTransitiveMemberOf -OrgContactId "<ContactId>").Id | ForEach-Object { (Get-MgGroup -Filter "id eq '$_'").DisplayName } 
$groupMemberships = $groupNames | ForEach-Object { "$contactName belongs to group $_" } | ForEach-Object { Write-Host $_ -ForegroundColor Green }

 

Retrieve Office 365 Contacts of a Specific Group

Sometimes, admins might have to send invitations to external contacts to access your organization’s resources. At times, rather than sending it to each contact individually, it can be more efficient to share the invitation with the entire group that your external contacts are a part of. Therefore, to find out whether the required contacts are present within a specific group, you can use the below script and retrieve all the contacts for a particular group.  

In short, this approach streamlines the process of ensuring the right individuals receive the necessary access, simplifying communication and resource sharing. 

$groupId = "<Group Id>"  
$members = Get-MgGroupMember -GroupId $groupId  
$contacts = foreach ($member in $members) {  
    Get-MgContact -Filter "id eq '$($member.Id)'" |  
    Select-Object DisplayName, Mail, JobTitle 
} 
$contacts | Export-Csv -Path "<C:\ ContactsInaGroup.csv>" -NoTypeInformation
