This Group Policy object (GPO) is inaccessible because you do not have the read-level permission on it

If you lost permissions to a GPO, obviously you cannot edit the GPO in Group Policy Management Console (GPMC). You would get this error: This Group Policy object (GPO) is inaccessible because you do not have the read-level permission on it.

Don’t you worry. There is an easy fix as long as you are a domain admin.

  • Open ADSIEdit.msc console
  • Right click on ADSI Edit and select “Connect to…”. Choose “Default Naming Context” and click OK.
  • Expland to ADSI Edit >>> Default Naming Context ( >>> DC=company,DC=com >>> System >>> Policies
  • Find the GUID of the GPO you lost access in Group Policy Management Console. Select the GUID of the Policy under CN=Polices OU.
  • Right click on Policy and choose Properties.
  • Select Security Tab and Click Advanced Button.
  • Take ownership of the policy by changing the owner to yourself (or better to Domain Admins). Close the properites dialog box.
  • Right click on the Policy and open Properties again.
  • Go to Security Tab. I would suggest to add permissions by copying the default permissions from other policy.
  • You may close the ADSI Edit console.

That’s all. After permissioning try accessing the GPO in GPMC.

GPEdit.msc – Failed to open the Group Policy Object on this computer

I see you end up here because local policy editor (GPEdit.msc) is failed to open and you get this error: Failed to open the Group Policy Object on this computer. You might not have the appropriate rights.

This super easy fix might fix the issue. All you have to do is rename (or delete) the folder named Machine at C:\Windows\System32\GroupPolicy.

I would rename the Machine directory to Machine.old. Then try launching gpedit.msc again.

Excel: BLOCKED CONTENT Macros in this document have been disabled…

You have downloaded an Excel document with macros from (known/excepted) website. When you open this Excel file, you get this error: BLOCKED CONTENT Macros in this document have been disabled by your enterprise administrator for security reasons.

There is a possibility System Administrator might have created a GPO to block Macros. If not, there is a easy solution to enable macros in Excel files (that is downloaded or received in Email).

Trust (Unblock) the file and open it in Excel again. Find the Excel file in Explorer, right on the file and open Properties. Check the box for Unblock the file and lick OK to save the setting, like this:

Now, open the Excel document and click on Enable Content button. That’s IT. Enjoy.

Solution: “The Feature You Are Trying to Use in on a Network Resource That is Unavailable”

Other day Zoom Outlook add-in was trying update itself and keep failing with “The Feature You Are Trying to Use in on a Network Resource That is Unavailable”. It keep asking for downloaded setup/MSI file.

Well…I found the solution that works for me; deleting a Freaking Registry Key. Here it is:

  • Open Registry Editor
  • Go to HKEY_LOCAL_MACHINE >> SOFTWARE >>  Classes >> Installer
  • Find the installing software/program name in the hive under Installer key.(e.g., for software find it under Products, for Microsoft update find it under Patches).
  • Once you find the GUID for the failed software install, Select it and Freaking Delete IT.

Try installing the software again.

PowerShell: Duplicate file finder ( by File Hash)

There are plenty of software on the market to find duplicate files. Almost all of them list the duplicates and have you review and delete them ONE by ONE. So I decided to write my own PowerShell script to
* Find the duplicates by file hash
* move the duplicate files to the given location

With a single click, moving the duplicates to a directory was most easy way to deal with duplicates. (I select the files and delete them at once).

Here is the script (example is in the comment section). ENJOY!

  ___                       ___  
 (o o)                     (o o) 
(  V  ) Duplicate Remover (  V  )

This script finds the duplicate files by
file hash and MOVE the duplicate files to
a given location. 

You can late review and delete all 
duplicate files from the given location.

Script written by: Anand, the Awesome

Path : Directory Path of the files where do you want to check the duplicates
DuplicateFileMoveLocation: Directory Path where to move the duplicate files. If this
directory doesn't exist, it will be created.

.\DuplicateFinder.ps1 -Path C:\Temp\Myfiles -DuplicateFileLocation C:\Temp\Myfiles\Duplicates

$DuplicateFileMoveLocation = "")

Write-Host "Calculating number of files in $path..." 
$TotalCount = (Get-ChildItem $Path).Count
Write-Host $Path "have " $TotalCount " files."
Write-Host "Started finding the Duplicates..."
# Get all duplicate files
$DuplicatePaths = 
    Get-ChildItem $Path -File | 
    Get-FileHash |
    Group-Object -Property Hash |
    Where-Object -Property Count -gt 1 |
    ForEach-Object {
        Write-Host "Duplicated File: $($_.Group.path)" -ForegroundColor Yellow
        $_.Group.Path | Select-Object -First ($_.Count -1)

Write-Host ($DuplicatePaths.Count) " Duplicate Files found. `n"
Write-Warning ("The Script found the {0} duplicate files out of {1} total. The duplicates will be moved to {2}." -f $DuplicatePaths.Count, $TotalCount,$DuplicateFileMoveLocation)
$answer = Read-Host -Prompt "Do you want to Proceed (Y or N)?"

if ($answer -eq 'y') {
    if ($DuplicateFileMoveLocation -ne "") { 
        # Create the duplicate file move directory if it does not exist.
        if ((Test-Path -Path $DuplicateFileMoveLocation) -eq $false) {New-Item -Path (Split-Path $DuplicateFileMoveLocation -Parent) -Name (Split-Path $DuplicateFileMoveLocation -Leaf) -ItemType "directory" *> $null}
        # Move the duplicates 
        $DuplicatePaths | ForEach-Object { 
            Write-Host "Moving $($_) to $DuplicateFileMoveLocation..." -ForegroundColor Red
            Move-Item -Path $_ -Destination $DuplicateFileMoveLocation 
Write-Host "* * * Completed * * *" 
End of the Script

Office 365: How do convert Teams to an Office 365 Group?

I see there where plenty of sites/blogs explains how to convert an Office 365 group to a Teams. Super easy to change it using Teams client. I did not see any reference to other way around. If you find this blog, Good for you.

I see few users created “Teams” in Teams client. They wanted to use the Office 365 group mailbox for that Teams. With Client side settings, there is no options to do that at all. As an Exchange Administrator you can do it in PowerShell.

For every “Teams” created in Teams client, you will see an “Unified Group” aka “Office 365 Group” in Exchange. So all we have to do is change is unhide this Office 365 group for Exchange Outlook users. Here is how you do it (Make sure you connect to Exchange Online first) in PowerShell:

# Replace "TeamsName" with your name of the Teams in double quotes
Set-UnifiedGroup -Identity 'TeamsName' -HiddenFromExchangeClientsEnabled:$false -HiddenFromAddressListsEnabled:$false

After you set to False to both properties, The Teams will show up in Outlook under Groups in Mailbox tree if they are members. Give it plenty of time ( 30 mins ) to take effect of this setting change.

Did it help you? leave me a comment.

Exchange Online/OWA: Where is the HELL is “Send event invitations in iCalendar format” option?

Do you have IMAP/POP3 users? It amazes me to see the some stubborn users refused to use Microsoft Outlook on their Mac/Windows computers. They uses the limited featured IMAP client. Hey! Whatever makes you happy, I guess.

Are they looking for the option “Send event invitations in iCalendar format” in OWA settings? This options converts meeting requests into a iCalendar file attachment.

They are expecting to find the option under

OWA Settings >>> Mail >>> Accounts >>> POP and IMAP


OWA Settings >>> Mail >>> Sync email

User-added image
I am sure this is the OLD OWA UI.

Instead they are seeing this in the new OWA UI.

p Search settings 
E Mail 
View quick settings 
Crynpose and reply 
Junk email 
Customize actions 
Sync email 
Message handling 
Automatic rephes 
Retention policies 
Sync email 
POP optiom 
Let devices and apps use POP 
O Yes 
@ No 
Server narne: 
Port 993 
Encryption rnethod: TLS 
SMTP setting 
Server name: 
Port 587 
Encryption rnethod: STARTTLS
So, Where the HELL is “Send event invitations in iCalendar Format” option?

I have learned that user cannot change this settings anymore. BUT as an Exchange Administrator, YOU can change this setting behalf of the user. Here is the PowerShell Command (connect to Exchange Online first):

# Provide the identity as email address of the user
Set-CASMailbox -Identity -ImapForceICalForCalendarRetrievalOption:$true -ImapUseProtocolDefaults:$false

Ta..da! Now that stone age IMAP user will start receiving future meeting requests in iCalendar file attachment. Say Hi! to them behalf of me.

Office 365: How to restore deleted OneDrive in PowerShell?

If an employee leaves the company, few managers wants the OneDrive content of the ex-employee. Few occasions it is business critical to take the documents from ex-employees’ OneDrive and re-share it again.

So how do you do that? I wrote the following script that does exactly that.

Before you run the script, make sure you have installed SharePoint Online module. Here is the help: Get started with the SharePoint Online Management Shell | Microsoft Docs

Note: Deleted OneDrive will be purged after 90 days. You can only restore the deleted OneDrive within 90 days of disabled date.

    Script to 
    1. Restore the deleted OneDrive
    2. Assign the Restored OneDrive to manager or another employee

    IMPORTANT:  Replace the OneDrive URL for the variable $DeletedUserOneDriveURL and 
    admin URL in Connect-SPOService's URL parameter.

    DeletedUsername : ex-employees' username or alias (Usually the name in the email address)
    NewUserEmail: Who needs to have access to the restored deleted OneDrive

     .\Restore-DeletedOneDrive -DeletedUsername JohnDoe -NewUserEmail



Function Connect-ProofpointSharePoint
    Import-Module Microsoft.Online.SharePoint.PowerShell
    Connect-SPOService -Url 

    -*-*-*-*-*-*-* The Script Starts Here -*-*-*-*-*-*-*-*-*-*

    IMPORTANT:  Repalce the OneDrive URL for the variable $DeletedUserOneDriveURL

    Example OneDrive URL:
    In this example, "acme" is the company's Office 365 tag. The email address 
    is converted to  username_acme_come in the end of the URL. If you are in doubt, visit
    your OneDrive in Browser, Copy the URL from teh address bar and use it here.

$DeletedUserOneDriveURL = "" + $DeletedUsername + "_acme_com"

# This command will ask for user credentials
"Connecting to SharePoint Online..."

"Restoring the OneDrive: $DeletedUserOneDriveURL" 
Restore-SPODeletedSite -Identity $DeletedUserOneDriveURL

"Assigning $NewUseremail to the Deleted OneDrive"
Set-SPOUser -Site $DeletedUserOneDriveURL -LoginName $NewUserEmail -IsSiteCollectionAdmin $True

# -*-*-*- End of the Script -*-*-*-*-*-*

If you need to check if the “Deleted OneDrive” is already purged or not, check with these commands:

#Connect to SharePoint Online : Replace "acme" with your company's Office 365 tag

Connect-SPOService -Url

# List all deleted sites includes OneDrive. Note "Days Remaining" the last column shows how many days left for purging

Get-SPODeletedSite -IncludePersonalSite

# List only the specific user

Get-SPODeletedSite -IncludePersonalSite | ? {$_.url -like '*JohnDoe*'}

I am sure this script and SharePoint commands will be helpful to you. Enjoy.

New kind of fresh HELL: Problem Ejecting USB Attached SCSI (UAS) Mass Storage Device. This device is currently in use

I ran into this issue of not able to eject an USB disk. Before you ask the question, I have set the disk for “Better Performance”. So I have to eject the disk before I remove it. (FYI, I would suggest to use “Better Performance” for bigger disks like 1TB or above to get most performance).

Now back to the issue, I was trying to eject the disk I am keep getting this error: “Windows is unable to stop the device” or “This device is currently in use”.

See the source image
See the source image

I freaking closed all the programs/windows, even killed explorer.exe from Task Manager. I tried logged out and logged back in.

If you run into this issue, I have a fix for you. Thank me later.

  1. Open Disk Management console (either run diskmgmt.msc in Run dialog – Windows Key + R, OR Right click on Start Menu and choose Disk Management).
  2. Find your disk in Disk Management console. Right click on the disk and choose Eject.

If you don’t see Eject, you may see “Offline” option. Then choose Offline, then remove the disk. Next time you connect this disk, you have to go to back to Disk Management and make it Online.

Tip- Disable/Enable web cam at will by PowerShell

Here is the one-line code to enable or disable the web cam when you want. Here is how it works.

I wrote a one line code and save it as a PowerShell (.ps1) file. Created a batch file to call the PowerShell script files to enable or disable the web cam.


Open PowerShell and type (or copy/paste). This will display all of your Camera device(s).

Get-PnpDevice | ? {$PSItem.Class -eq 'Camera'} | fl FriendlyName,InstanceId
Here is the example:
E:> Get-PnpDevice | ? {$PSItem.Class -eq 'Camera'} | fl FriendlyName,InstanceId
 FriendlyName : Integrated Camera
 InstanceId   : USB\VID_04CA&PID_703C&MI_00\7&36726615&0&0000
 FriendlyName : S-YUE 8MP USB Camera
 InstanceId   : USB\VID_0BDA&PID_5075&MI_00\8&3E5D74C&0&0000

Now note down the Instance ID of the current camera (copy it to the clipboard).

Creating the PowerShell and Batch files

Disable Script

  1. PowerShell script file

Type the command below in a Notepad/Editor and replace the InstanceID you noted down above.

Disable-PnpDevice -InstanceId 'USB\VID_0BDA&PID_5075&MI_00\8&3E5D74C&0&0000' -Confirm:$false

Save the file as Disable-Camera.ps1.

2. Batch file

Type the command below in a Notepad/Editor and replace the path of your Powershell Scirpt file. Save the file as Disable-Camera.bat

PowerShell.exe -Command "C:\Temp\Disable-Camera.ps1"

Enable Script

  1. PowerShell script file

Type the command below in a Notepad/Editor and replace the InstanceID you noted down above.

Enable-PnpDevice -InstanceId 'USB\VID_0BDA&PID_5075&MI_00\8&3E5D74C&0&0000' -Confirm:$false

Save the file as Enable-Camera.ps1.

2. Batch file

Type the command below in a Notepad/Editor and replace the path of your Powershell Scirpt file. Save the file as Enable-Camera.bat

PowerShell.exe -Command "C:\Temp\Enable-Camera.ps1"

How to use it?

Here are my created files:

I made the shortcut for the Batch file on my desktop. When I needed, I right-click on the shortcut icons, select Run as Administrator.

To enable or disable the device, script has to run in elevated PowerShell. That’s why you have to run the shortcut Run as Administrator.

Better yet, I use Circle Dock to quickly launch programs. So I created two new icons for it.
