This PowerShell script will let you loop through each SharePoint Online site to perform a specific action. I’ve been asked a couple of times to write a script to for example create a new document library in each site, add a web part or grant permissions. I always start with the below script so I only need to write the desired action and don’t need to worry about doing this for each site. Please let me know if you have used my script, for what purpose and if there are any questions.

Running the script

We will first start by opening the SharePoint Online Management Shell as administrator which can be downloaded at https://www.microsoft.com/en-us/download/details.aspx?id=35588.

 

 

 

 

You will only need to add the action below the start and above the comment section and it will run for each site. Just copy and paste the full script.

function Update-SPOWeb ($web){
#Get Web information and subsites
$context = New-Object Microsoft.SharePoint.Client.ClientContext($web)
$context.Credentials = $SPOCredentials
$web = $context.Web
$context.Load($web)
$context.Load($web.Webs)

#send the request containing all operations to the server
try{
$context.executeQuery()

#check any subweb if present
if ($web.Webs.Count -ne 0){
foreach ($subweb in $web.Webs){
Update-SPOWeb($subweb.url)
}
}

function Update-SPOWebs{
#variables that will be asked during the script
$adminUrl = Read-Host "Please enter the Office365 Admin URL (e.g. https://spfire-admin.sharepoint.com)"
$webUrl = Read-Host "Please enter the start url (e.g. https://spfire.sharepoint.com/sites/rootsite"

try{
