Syntax

Remove-ADGroup [-Identity] <ADGroup> [-Confirm] [-Server <string>]

### Key Parameters

## Important Notes

- **Cannot delete group with members** - Must remove all members first
- **Affects permissions** - Users lose group-based permissions
- **Cannot undo easily** - Group GUID is never reused; restore from backup if needed

## Examples

### Example 1: Delete Group with Confirmation

```powershell
Remove-ADGroup -Identity "OldGroup"
```powershell

**Output:** Prompts for confirmation before deleting

### Example 2: Delete Without Confirmation

```powershell
Remove-ADGroup -Identity "OldGroup" -Confirm:$false
```powershell

### Example 3: Remove Group and Members First

```powershell
$group = Get-ADGroup "OldGroup"

# Remove all members
Get-ADGroupMember -Identity $group |
Remove-ADGroupMember -Identity $group -Confirm:$false

# Then delete group
Remove-ADGroup -Identity $group -Confirm:$false
```powershell

### Example 4: Delete Empty Groups

```powershell
Get-ADGroup -Filter * -Properties Members |
Where-Object { -not $_.Members } |
Remove-ADGroup -Confirm:$false
```powershell

### Example 5: Delete Groups by Pattern

```powershell
Get-ADGroup -Filter "name -like '*test*'" |
Remove-ADGroup -Confirm:$false
```powershell

### Example 6: Bulk Delete from CSV

```powershell
$csv = Import-Csv "C:\groups-to-delete.csv"

foreach ($item in $csv) {
    try {
        # Remove members first
        Get-ADGroupMember -Identity $item.GroupName |
        Remove-ADGroupMember -Identity $item.GroupName -Confirm:$false -ErrorAction SilentlyContinue

        # Delete group
        Remove-ADGroup -Identity $item.GroupName -Confirm:$false
        Write-Host "✓ Deleted: $($item.GroupName)"
    }
    catch {
        Write-Host "✗ Failed: $($item.GroupName) - $($_.Exception.Message)"
    }
}
```powershell

### Example 7: Delete Distribution Lists

```powershell
Get-ADGroup -Filter "groupCategory -eq 'Distribution'" |
Where-Object { $_.Name -like "*Old*" } |
Remove-ADGroup -Confirm:$false
```powershell

### Example 8: Safe Deletion with Backup

```powershell
$group = Get-ADGroup "OldGroup" -Properties *

# Backup group info
$group | Export-Clixml -Path "C:\backups\$($group.Name)-backup-$(Get-Date -Format 'yyyy-MM-dd').xml"
Write-Host "Backed up: $($group.Name)"

# Remove members
Get-ADGroupMember -Identity $group |
Remove-ADGroupMember -Identity $group -Confirm:$false

# Delete group
Remove-ADGroup -Identity $group -Confirm:$false
Write-Host "Deleted: $($group.Name)"
```powershell

### Example 9: Delete with Error Handling

```powershell
try {
    Remove-ADGroup -Identity "TestGroup" -Confirm:$false -ErrorAction Stop
    Write-Host "✓ Group deleted successfully"
}
catch {
    if ($_.Exception.Message -like "*cannot be deleted*") {
        Write-Host "✗ Group has members - remove members first"
    }
    else {
        Write-Host "✗ Error: $($_.Exception.Message)"
    }
}
```powershell

### Example 10: Audit Before Deletion

```powershell
$group = Get-ADGroup "OldGroup" -Properties *

Write-Host "Group Details:"
Write-Host "  Name: $($group.Name)"
Write-Host "  Description: $($group.Description)"
Write-Host "  Members: $($(Get-ADGroupMember -Identity $group).Count)"
Write-Host "  CreatedDate: $($group.Created)"

Remove-ADGroup -Identity $group
```powershell

## Best Practices

✅ **Remove members first** - Clean up before deletion
✅ **Backup group info** - Export before deleting
✅ **Audit permissions** - Check what permissions group has
✅ **Log deletions** - Record what was deleted
✅ **Confirm with owners** - Verify group is truly unused
✅ **Use -Confirm** - Prompt before deleting important groups

### Common Mistakes
- Deleting groups with members still assigned
- Not backing up before deletion
- Using -Confirm:$false without verification
- Deleting wrong group
- Not checking permissions before deletion
