How to Set Storage Quota for Office 365 Groups in SharePoint Online

Featured image

In our previous blog, we dealt with how to track the storage used by Office 365 groups. Since Office 365 Groups’ files consume the storage space from the quota allocated for Site Collections in a SharePoint Online tenant, for more information refer thislink. So in this blog we share the steps to limit the storage used by Office 365 Groups’ files by setting Storage Quota for Office 365 Groups using PowerShell.

Before starting the process, download and install the SharePoint Online Management Shell from this link. Then execute the script in PowerShell (with Run as Administrator privilege) by connecting to SharePoint Online as Global administrator. Also ensure that the SharePoint online setting “Site Collection Storage Management” is set as Manual.

How to Set Storage Quota for a Specific Office 365 Group

Following PowerShell script is used to Set Storage Quota for a Specific Office 365 Group. This script uses “Set-SPOSite” to set StorageQuota and StorageQuotaWarningLevel for a Specific Office 365 Group in the SharePoint Online tenant. Finally after setting storage quota, following information will be displayed as result: GroupName, StorageQuotaWarningLevel, CurrentStorage, and StorageQuota.

NOTE: It is recommended to execute the below script as .ps1 file with elevated privilege (Run as Administrator).

Copy the below script to notepad and save it as .ps1 file or download .ps1 file from here

Step1: Get values for input parameters

$SPOAdminCenterUrl=Read-Host "Enter the admin URL(https://domainanme-admin.sharepoint.com):"
$Quota=Read-Host "Enter the Storage Quota value in MB:"
$WarningQuota=Read-Host "Enter the Warning Storage Quota value in MB:"
$Gpname=Read-Host "Enter the Office 365 GroupName:"

Step2: Connect to SharePoint Online using “Connect-SPOService” cmdlet

Import-Module Microsoft.Online.SharePoint.Powershell -Verbose
$credential = get-credential 
Connect-SPOService -Url $SPOAdminCenterUrl -Credential $credential

Step3: Connect Exchange Online

$Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri
https://ps.outlook.com/powershell -Credential $credential -Authentication Basic -AllowRedirection
Import-PSSession $Session

Step4: Set Storage Quota for a Specific Office 365 Group

$Group=Get-UnifiedGroup $Gpname -Erroraction SilentlyContinue
If($Group -ne $null)
{
$GName=$Group.Alias
$SiteURL=$Group.SharePointSiteUrl
If($SiteURL -ne $null){
Set-SPOSite -Identity $SiteURL -StorageQuota $Quota -StorageQuotaWarningLevel $WarningQuota
$site=Get-SPOSite -Identity $SiteURL -Detailed
      New-Object -TypeName PSObject -Property @{
      GroupName=$GName
      CurrentStorage=$site.StorageUsageCurrent
      StorageQuota=$site.StorageQuota
      StorageQuotaWarningLevel=$site.StorageQuotaWarningLevel
}
}
Else
{
Write-Host "$($GName) Group Member never accessed Group File site. So $($GName) Group Site not Created." -ForegroundColor Green
}
}
Else
{
Write-Host "$($line.Groupname) Group name is Invaild" -ForegroundColor Red
}

Connect-SPOService -Url $SPOAdminCenterUrl -Credential $credential

Step3: To get all the Office 365 groups, we use “Get-UnifiedGroup” cmdlet, which depends on Exchange Online

$Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://ps.outlook.com/powershell -Credential $credential -Authentication 
Basic -AllowRedirection
Import-PSSession $Session
$Groups=Get-UnifiedGroup
$Groups | Foreach-Object{
$Group = $_
$GName=$Group.Alias
$SiteURL=$Group.SharePointSiteUrl
If($SiteURL -ne $null){
Set-SPOSite -Identity $SiteURL -StorageQuota $Quota -StorageQuotaWarningLevel $WarningQuota
$site=Get-SPOSite -Identity $SiteURL -Detailed
      New-Object -TypeName PSObject -Property @{
      GroupName=$GName
      CurrentStorage=$site.StorageUsageCurrent
