People picker settings for all Web Applications one-liner

Summary: This PowerShell one-liner will show the people picker settings for each Web Application, including Central Administration.

If you want to know the settings for the people picker in your SharePoint farm, you can run the following line of PowerShell.
It will retrieve all Web Applications and show the people picker settings for each one.

Get-SPWebApplication -IncludeCentralAdministration | %{Write-Host $_.url; $_.peoplepickersettings | select * | fl }

Running the one-liner will result in something like this:

Change site collection URL in SharePoint 2013

Summary: This post describes the different ways to change the site collection URL in SharePoint 2013.

So, your manager/the business asks you to create a few site collections for some departments in your organization. You quickly spin up some site collections for them to use. After a few weeks, the business decides (of course) SharePoint is great, but the URL’s we chose weren’t all that great. Can you please change them?

There are alot of blog posts out there that describe the different possibilities in this scenario:
– Using backup and restore.
– A great article by Todd Klindt that tells you how to use the Copy-SPSite cmdlet to achieve the same goal but easier!

There is another (easier) way in some scenario’s in which you can change the site collection URL by just using 2 lines of PowerShell with only a second of waiting time!

The solution
Let’s get down to it.. I created this very nice Marketing site collection, using the url: http://sharepoint/sites/marketing. Now I would like to change this to http://sharepoint/sites/sales. Just use the following 2 lines of PowerShell code and you are done!

 $site = Get-SPSite http://sharepoint/sites/marketing

That is all.. try it out and see that your new URL is working, and the old URL is not working anymore!
*NOTE* Thanks to Jaymeson in the comments for pointing out an IISRESET is needed as well!

A little catch
There is a little catch to this. You can only use this to rename site collection URL’s that
– Use “Wildcard inclusion” Managed Paths.
– Are Host named site collections (In which case you could also use Set-SPSiteURL)

You can’t use it to change http://sharepoint/sites/marketing to http://sharepoint/marketing (Even if the Explicit inclusion managed path exists).

Hope this helps anyone out there!

Download content from a site collection

I’ve been working on a script that will allow you to download all files that are stored in SharePoint in a given site collection.

If the path does not exist, the script will prompt you to create it for you. Before the script runs, it also checks if the site collection exists.

Run the script like this:

.\Get-SPContent.ps1 -SiteCollection "<SiteCollectionURL>" -Destination "<Path>"

Download content

The console shows which libraries were exported to your file system.

—– * Advanced * —–

If you have specific requirements as to which (type of) libraries you want to export, you can change the following line to fit your requirements:

$lists = $web.lists | ?{$_.itemcount -ge &quot;1&quot; -And $_.Hidden -eq $false -And $_.BaseType -eq &quot;DocumentLibrary&quot;} #Excludes all hidden libraries and empty libraries

Below is the code you can save as Get-SPContent.ps1

[ValidateScript({asnp *sh* -EA SilentlyContinue;if (Get-SPSite $_){$true}else{Throw &quot;Site collection $_ does not exist&quot;}})]
if (Test-Path $_)
$d = $_
$title = &quot;Create Folder?&quot;;
$message = &quot;$_ doesn't exist, do you want the script to create it?&quot;;
$yes = New-Object System.Management.Automation.Host.ChoiceDescription &quot;&amp;Yes&quot;, &quot;Creates directory $_&quot;;
$no = New-Object System.Management.Automation.Host.ChoiceDescription &quot;&amp;No&quot;, &quot;Exits script&quot;;
$options = [System.Management.Automation.Host.ChoiceDescription[]]($yes,$no);
$result = $host.ui.PromptForChoice($title,$message,$options,1);
0 {New-Item $d -Type Directory;$true}
1 {Throw &quot;Please create the folder before running the script again. `nExiting script&quot;}

Asnp *sh* -EA SilentlyContinue

Write-Host &quot;- $($list.RootFolder.url)&quot;

#Download files in root folder
$rootfolder = $web.GetFolder($list.RootFolder.Url)

#Download files in subfolders
foreach($folder in $list.folders)
$folder = $web.GetFolder($folder.url)



function Download-SPContent($folder)
foreach($file in $folder.Files)
$binary = $file.OpenBinary()
$stream = New-Object System.IO.FileStream($destination + &quot;/&quot; + $file.Name), Create
$writer = New-Object System.IO.BinaryWriter($stream)

$webs = Get-SPWebs -SiteCollection $Sitecollection

Add-PSSnapIn Microsoft.SharePoint.PowerShell shortcut

Are you tired of typing Add-PSSnapIn Microsoft.SharePoint.PowerShell every time you open your PowerShell console?
You can do this by Adding/Editing profile.ps1 (I don’t do this because I have too many machines where I should change this)

If you find you do not want to change the profile.ps1 on every server you are working on, you can type this:

asnp *sh*

This adds all SnapIns that contain *sh*. In most cases, this will only add the Microsoft.SharePoint.PowerShell SnapIn.

Happy PowerShelling!


Restore deleted site collections SharePoint 2013

In SharePoint 2013 it is possible to restore a deleted site collection. For more information, read this article:

You can use the Restore-SPDeletedSite cmdlet to restore a site collection.

However, if you removed the site collection using the Remove-SPSite cmdlet using PowerShell, the site collection will not be stored in a SPDeletedSite object.

This means you cannot restore a site collection that has been removed using PowerShell.


Add PDF mimetype for all Web Applications oneliner

By default, PDF files cannot be opened directly from SharePoint 2010/SharePoint 2013.

To add the PDF mimetype to all Web Applications (Instead of doing it seperately for each Web Application), you can use the following oneliner:

Get-SPWebApplication | %{$_.AllowedInlineDownloadedMimeTypes.Add("application/pdf");$_.Update()}

Get all subsites of a subsite using PowerShell

Getting a list of all subsites of a particular site (not a site collection) was a little more work than I expected, so here is how I did it.

Let’s say we have the following situation site structure:


What if we want an overview of all sites under “Https://”?

My first thought was to use the “Webs” property of the SPWeb object. Unfortunately, this only shows the direct subsites for this site. This means that for “Https://”, it only shows the Level 3 sites.


To work around this, I used the “AllWebs” property of the SPSite object and filtered the URL’s starting with “Https://”.

Here is the code used: (Download .zip file)

param ( [Parameter(Mandatory=$true)][ValidateNotNullOrEmpty()] [String]$StartWeb, [Boolean]$IncludeStartWeb = $true )

Add-PSSnapin Microsoft.SharePoint.PowerShell -ErrorAction SilentlyContinue

$subsites = ((Get-SPWeb $StartWeb).Site).allwebs | ?{$_.url -like "$StartWeb*"}

foreach($subsite in $subsites) { Write-Host $subsite.url }

As you can see in the source code, I added 2 parameters to the script:

StartWeb: String. This is the starting URL. All subsites under this site will be showed in the result.

IncludeStartWeb: Boolean. When set to $false, the output will not include the URL provided in the StartWeb parameter.

Remove users from User Information List (people picker) using PowerShell

This post will describe how you can remove users in bulk from the User Information List using a PowerShell script and a simple CSV file.

In SharePoint 2010, the people picker retrieves data from multiple sources.

– The Site Collection’s User Information List (UIL);
– Active Directory.

When you delete a user from Active Directory, this will not mean the user isn’t searchable in SharePoint. Actually, if you look for this person in the people picker, you will probably find him/her. As the data is pulled from different sources, there may be several causes for this.

Assuming the user is really deleted from the Active Directory, I will give you some pointers as to how to “delete” the users from the People picker.

I have a user called Kim Akers in my Contoso environment. She has permissions on several sites/subsites, and placed documents and list items in multiple places.

Example site

She also has a MySite.


For some reason, Kim is fired. The Active Directory administrators remove her account from Active Directory.

However, when I look at the People Picker in SharePoint, I can still find this user.

People picker

Why is this happening?

Every user that is given direct permissions, or has logged in to SharePoint, will be added to the Site Collection’s User Information List. This is a hidden list, that you can access by going to your site collection’s URL and add /_catalogs/users/simple.aspx. For instance:

This will show a list of all users that have logged in on your SharePoint. Sure enough, Kim can still be found here, even though her account has been deleted in Active Directory.

User Information List


To remove the user from the information list, you can use the GUI. If you want more information on how to do this, read this article. Also, make sure the profile for this user is not in the Profile Database. You can remove users from the Profile Database directly by going to Central Administration -&> Application Management -&> Manage Service Application -&> Click your User Profile Service Application -&> Manage User Profiles -> Find profile by entering the name -> Select the name in the list, and click Delete.

In my case, I wanted to remove a list of users from All site collections, because I am certain that these users will never log in again, and I don’t want them to show in the people picker. The below script will do just that!

[Parameter(Mandatory=$true)][ValidateScript({Test-Path $_ -Include "*.csv"})]

#This script will remove users specified in the CSV.

$CSVFile = Import-CSV $CSVPath
Add-PSSnapin Microsoft.SharePoint.PowerShell -EA SilentlyContinue

#Get all site collections
$Sites = Get-SPSite -Limit All
$AllSites = @()
foreach($Line in $CSVFile)
foreach($Site in $Sites)
#Get the rootweb for the site collection
$RootWeb = $Site.RootWeb
If([bool](Get-SPUser $Line.Username -Web $RootWeb -EA SilentlyContinue) -eq $True)
#Remove the user from the User Information List
Remove-SPUser -Identity $Line.username -Web $RootWeb -Confirm:$False
$AllSites += $RootWeb.Url
if(!($AllSites).count -eq 0)
#Give feedback on deleted users
Write-Host "Removed user $($Line.username) from:" -Fore "Magenta"
foreach($S in $AllSites){Write-Host "- $S"}
Write-Host ""
$AllSites = @()

I save the above text in a .ps1 file called Remove-SPUserBulk.ps1.

Next, I create a CSV file (Users.csv) that will contain all the users that I want to remove. My demo CSV looks like this:


As you can see, I added a non-existing account, to show that the script actually just deletes the existing user, and the output is correct. I run the script by going to the location where the Remove-SPUserBulk.ps1 file is located, and enter: “Remove-SPUSerBulk.ps1 -CSVPath “C:scriptsUsers.csv”.

Below is the result.


Be aware that if the user is a site collection administrator, you will get an error stating you cannot delete the owners of a Web site collection.

Site collection creation time using PowerShell

This script will show you the site collection creation time for each site collection using PowerShell.
Try the following oneliner to get all the information you need:

Get-SPSite -Limit All | %{$root = $_.rootweb; $date = $root.created.toShortDateString(); Write-Host "$($root.url) was created on $($date)"}

Site collection creation time

Change site collection administrators using PowerShell

In a minute, I will show you how to change the site collection administrators for all site collections using PowerShell. Thanks to Maarten Peeters for helping!

But first, it may be easy to get a result for all the current site collection administators, in case you want to roll back:

Get-SPSite -Limit all | FT Url, Owner, SecondaryContact -AutoSize

Site collection administrators

Now if you want to change all site collection administrators and secondary site collection administrators (As you would set in Central Administration)

Get-SPSite -Limit All | %{Set-SPSite $_ -OwnerAlias "<domainuser>" -SecondaryOwnerAlias "<domainuser>"}

If you are using MySites and personal sites have been created, you might want to use the following, to exclude the MySite site collections. Please check if you are using the “personal” managed path. If you are using a different managed path, you can change the “*/personal/*” to reflect your environment.

Get-SPSite -Limit All | ?{$_.url -notlike "*/personal/*"} | %{Set-SPSite $_ -OwnerAlias "<domainuser>" -SecondaryOwnerAlias "<domainuser>"}

I hope this helps someone out there to save some valuable time!
