Remove AzureAD user from all groups -powershell-CodePudding

I've been trying to remove all of the groups(M365,DL,security etc.) from a user. I was trying to use this script but I'm getting errors when removing DLs(reasonably).

$Groups = Get-AzureADUserMembership  -ObjectId $userID 
foreach($Group in $Groups.ObjectId){
Remove-AzureADGroupMember -ObjectId $Group -MemberId $userID 
}

My problem is that I have no way to get the type of the group and treat it with the correct command accordingly. When trying to use MSOL to get the type I saw that M365 groups are also being shown as a distribution list, So I'm not able to use this method.

Any advice or luck with that? Thanks!

Edit: This is how the groups are showing up, identical but not actually as it requires different command to remove the group. 365 group and DL

I have tried with same script in my environment to remove an user from the groups and it removed successfully .

Azure portal->Groups->Enter your Group name

In my Azure Active directory ,I have Microsoft group type with 5 users:

In my Security Group type I have 4 users:

enter image description here I tried with particular user like imran khan to remove from these two groups.

First you need to connect with azureAD using this command :

Import-Module AzureAD
$Credential = Get-Credential
Connect-AzureAD -Credential $Credential

Now I tried with same commands:

$userID = 'user object ID'
$Groups = Get-AzureADUserMembership  -ObjectId $userID 
foreach($Group in $Groups.ObjectId){
Remove-AzureADGroupMember -ObjectId $Group -MemberId $userID 
}

enter image description here

Response: enter image description here

Which returned empty that means which I removed successfully a user from the group.

Reference: Compare groups - Microsoft 365 admin | Microsoft Docs

Considering that Azure AD group memberships can be removed via Remove-AzureAdGroupMember while Exchange Online memberships via Remove-DistributionGroupMember, executing both commands via a try..catch is probably the most efficient way to meet the OP's requirements. The code below does just that (remove the comment before the Confirm parameter to skip confirmation.)

Connect-AzureAD
Connect-ExchangeOnline

$userid = (Get-AzureADuser -objectid "[email protected]").objectid

$Groups = Get-AzureADUserMembership -ObjectId $userID 
foreach($Group in $Groups){ 
    try { 
        Remove-AzureADGroupMember -ObjectId $Group.ObjectID -MemberId $userID -erroraction Stop 
    }
    catch {
        write-host "$($Group.displayname) membership cannot be removed via Azure cmdlets."
        Remove-DistributionGroupMember -identity $group.mail -member $userid -BypassSecurityGroupManagerCheck # -Confirm:$false
    }
}

Note: proper code formatting does help.
