Take Ownership and Grant ‘Full Control’ Recursively

Take Ownership KB ID 0001200 

Problem

I had a bunch of old user profile folders I needed to delete today, When setup properly even the domain administrator can’t get in there and delete them;

You need permission to perform this action.

You don’t currently have persmission to access this folder

If it’s just one folder then simply take ownership, grant yourself rights and delete it! But I had a lot of folders so I needed a more robust (read less work) solution.

Solution: Take Ownership

Take Ownership of all Folders/Sub-Folders, and Files

Open an administrative command window, and execute the following command;

[box]

takeown /a /r /d Y /f C:\"Path-To-Folder"

[/box]

Grant ‘Full Control’ Rights to all Folders/Sub-Folders, and Files

Just because you are the owner, that does not mean you have any rights to the folders and files, to grant full control to the administrators group.

[box]

icacls C:\"Path-To-Folder" /grant administrators:F /t

[/box]

You can then delete the folder and its contents recursively with the following command.

[box]

Remove-Item -Path "Path-To-Folder" -Force -Recurse

[/box]

Powershell: Get Folder Size ‘Quickly’

Problem

Right clicking a folder and selecting properties is usually how you would see how large a folder is. Which is great, but if your folder size is HUGE (i.e. many terabytes) then this takes ages!

Solution

If you use PowerShell you can get the figure considerably quicker! Below I want to ge the size of E:\Shared;

[box]

In MegaBytes;
"{0:N2}" -f ((Get-ChildItem -path E:\Shared -recurse | Measure-Object -property length -sum ).sum /1MB) + " MB"

In GigaBytes;
"{0:N2}" -f ((Get-ChildItem -path E:\Shared -recurse | Measure-Object -property length -sum ).sum /1GB) + " GB"

In TeraBytes;
"{0:N2}" -f ((Get-ChildItem -path E:\Shared -recurse | Measure-Object -property length -sum ).sum /1TB) + " TB"

[/box]

You can even save this as a ‘function’ then call it whenever you wish.

[box]

function Get-FolderSize
{
 param([string]$pth)
 "{0:N2}" -f ((gci -path $pth -recurse | measure-object -property length -sum).sum /1GB) + " GB"
}

[/box]

Adding Rights to Public Folders (Recursively)

Posted on by

KB ID 0001598

Problem

After a recent Exchange migration (2007 > 2013 > 2016), I had problems with users not being able to see public folders, one user could see them all, (so I know they were present and correct, content wise,) but other users could not even see them.

Normally in this situation I’d test them in Outlook Web App first, if they work there then look at Outlook, but Public folders just didn’t work in Outlook Web App 2016 at all.

My first task was to check/set the permissions of the public folders, the one user who could see them was set as ‘Owner‘ on the root of the public folders, so my first step was working out how to grant myself these rights, and apply all those rights to all the child public folders below?

Note: Granting a user ‘Owner‘ rights at the root has obvious security implications, in your scenario you might want to choose ‘Reviewer’, or some other level of access.

View Existing Public Folder ‘Root’ Permissions

Simply use the following PowerShell in the Exchange Management Shell;

[box]

Get-PublicFolderClientPermission "\"

[/box]

If you just wanted to check for one user, then do this instead;

[box]

Get-PublicFolder -Identity "\" -Recurse | Get-PublicFolderClientPermission | Where-Object { $PSItem.User -like "SURNAME*" }

[/box]

Note: If you are working on a particular ‘child’ Public Folder the the syntax is “\FOLDER NAME“.

Granting Public Folder Rights Recursively

Use the following PowerShell in the Exchange Management Shell

[box]

Get-PublicFolder -Identity "\" -Recurse | Add-PublicFolderClientPermission -User pete.long -AccessRights Owner

[/box]

It complains and says this user already has rights? If this happens then Recursively Remove all rights then re-execute the command above.

Removing Public Folder Rights Recursively

Use the following PowerShell in the Exchange Management Shell

[box]

Get-PublicFolder -Identity "\" -Recurse | Remove-PublicFolderClientPermission -User pete.long

[/box]
