Default storage limit for OneDrive online is 1 TB for all the Microsoft 365 users. SharePoint Admin can change the OneDrive’s storage quota limit from the OneDrive Admin Center but that would be for all users. If a user’s OneDrive is reaching the the 1 TB storage limit than SharePoint admin can increase the storage limit for that user using Microsoft 365 Admin Center and by using SharePoint online PowerShell.
User can view their storage limit by going to OneDrive Settings à More Settings and click on Storage Matrix.
A user can access his/her OneDrive’s URL directly through brownser by login into Microsoft 365 Tenant. A SharePoint Admin can access it through multiple ways which explained on this blog post. Below is a small PowerShell script which will return of all OneDrive sites
Import-Module Microsoft.Online.SharePoint.PowerShell $TenantUrl = "https://mstalk-admin.sharepoint.com" Connect-SPOService -Url $TenantUrl $OneDriveURLs = Get-SPOSite -IncludePersonalSite $true -Limit all -Filter "Url -like -my.sharepoint.com/personal/" | select Title,Url,Owner,StorageUsageCurrent| Out-GridView
Go to Active users and search for the user. Click on the user’s name for details and select OneDrive Tab and click on Edit button Under Storage used.
Use below SharePoint online PowerShell to update the storage limit for a user:
Import-Module Microsoft.Online.SharePoint.PowerShell $TenantUrl = "https://mstalk-admin.sharepoint.com" $OneDriveSite = "https://mstalk-my.sharepoint.com/personal/adnan_amin_mstechtalk_com" #Enter the OneDrive Storage Quota in MB $OneDriveStorageQuota = "2097152" #Enter the OneDrive Storage Quota Warning Level in MB $OneDriveStorageQuotaWarningLevel = "2097152" Set-SPOSite -Identity $OneDriveSite -StorageQuota $OneDriveStorageQuota -StorageQuotaWarningLevel $OneDriveStorageQuotaWarningLevel
