How to list all members of a Distribution group and their emails with PowerShell

This question came from the need of a user who needed to extract the following information:

Distribution Group Name | Group Email | Group Member | Member’s Email

 

Function Get-DistributionEmail

{

 

    # Get a list of all the distribution groups in the domain.

    $Groups = Get-ADGroup -Filter 'GroupCategory -eq "Distribution"' -Properties Mail

 

    # Create a dynamic array to hold the objects for the output.

    $Obj = @()

   

    # Loop through each group.

    ForEach ($Group in $Groups)

    {

        # Enumerate all the members of the group.

        $Members = Get-ADGroupMember -Identity $Group.name

       

        # Collect the data for the output.

        ForEach ($Member in $Members)

        {

            $GroupObj = New-Object PSObject

            $GroupObj | Add-Member `

             -MemberType NoteProperty `

             -Name "Group" `

             -Value $Group.Name

           

            $GroupObj | Add-Member `

             -MemberType NoteProperty `

             -Name "GroupEmail" `

             -Value $Group.Mail

 

            $GroupObj | Add-Member `

             -MemberType NoteProperty `

             -Name "User" `

             -Value $Member.Name

           

            $User = get-ADuser -filter 'Name -eq $Member.name' -Properties Mail

 

            $GroupObj | Add-Member `

             -MemberType NoteProperty `

             -Name "UserEmail" `

             -Value $User.Mail

 

             # Transfer the object to the dynamic array.

             $Obj += $GroupObj

        }

    }

    # Wrtie the contents of the array to the PowerShell pipeline.

    Write-Output $Obj | FT -AutoSize

Error icon when creating a GPO Preference drive map

You may not have an error at all.  Take a look at the drive mapping below. The red triangle is what threw us off.  It is not an error.  It is simply a color representation of the Replace option of the Action field in the properties of the drive mappings. Create action This give you a green triangle. The Create action creates a new mapped drive for users. Replace Action The Replace action gives you a red triangle.  This action will delete and recreate mapped drives for users. The net result of the Replace action is to overwrite all existing settings associated with the mapped drive. If the drive mapping does not exist, then the Replace action creates a new drive mapping. Update Action The Update action will have a yellow triangle. Update will modify settings of an existing mapped drive for users.
