Office 365 comes with 1 TB of storage per user in OneDrive for Business. You can use this space to store your documents, photos, and other files. It can be helpful to keep track of the storage consumption to ensure the most effective use of OneDrive sites. To get the storage quota data for a particular OneDrive site, use this PowerShell cmdlet in SharePoint Online Management Shell:

Get-SPOSite -Identity "https://crescent-my.sharepoint.com/personal/salaudeen_crescent_com"

This gets you the currently allocated storage quota data for a single site collection.

#Connect to SharePoint Online Admin Center
Connect-SPOService -Url $AdminSiteURL -credential $Cred

#Get all Personal Site collections and export to a Text file
$OneDriveSites = Get-SPOSite -Template "SPSPERS" -Limit ALL -includepersonalsite $True

$Result=@() 
# Get storage quota of each site
Foreach($Site in $OneDriveSites)
{
    $Result += New-Object PSObject -property @{ 
    URL = $Site.URL
    Owner= $Site.Owner
    Size_inMB = $Site.StorageUsageCurrent
    StorageQuota_inGB = $Site.StorageQuota/1024
    }
}

$Result | Format-Table

#Export the data to CSV
$Result | Export-Csv "C:\Temp\OneDrive.csv" -NoTypeInformation

How to Set Storage Quota for OneDrive Site Collection?

By default, OneDrive site collections in Office 365 come with a 1 TB storage quota. You may want to either increase or decrease the storage allocation in some situations. Say, you want to increase the storage quota for a particular OneDrive site collection to 2 TB:

Set-SPOSite -Identity "https://crescent-my.sharepoint.com/personal/salaudeen_crescent_com" -StorageQuota 2097152 

Similarly, the User’s OneDrive storage quota can be reset to the default OneDrive storage quota

Set-SPOSite -Identity "https://crescent-my.sharepoint.com/personal/salaudeen_crescent_com" -StorageQuotaReset
