docs/deployments/services/Microsoft 365/Seize Control of Personal OneDrive Data of Another User.md

Purpose

You may find that you need to access data from a user's personal OneDrive account, and since that data cannot be accessed directly via Office365's Admin Portal, you have to do some legwork in Powershell.

Connect to Sharepoint

Install-Module Microsoft.Online.SharePoint.PowerShell
Import-Module Microsoft.Online.SharePoint.PowerShell
Connect-SPOService -Url https://<companyname>-admin.sharepoint.com # Login with your Office365 Admin Credentials when Prompted

Display List of Personal Sharepoint Sites (OneDrive)

Get-SPOSite -IncludePersonalSite $true -Limit All

Check OneDrive Usage of the Given User

Get-SPOSite -Identity "https://<companyname>-my.sharepoint.com/personal/username_companyname_com" | Select Url, Owner, StorageUsageCurrent, StorageQuota, LastContentModifiedDate

Assign Yourself Permissions to Their OneDrive

Set-SPOUser `
-Site "https://<companyname>-my.sharepoint.com/personal/username_companyname_com" `
-LoginName "i:0#.f|membership|admin@companyname.com" `
-IsSiteCollectionAdmin $true

Navigate to Webpage

At this point, you now have permissions to access the OneDrive data, so open a web browser and navigate to the SPOSite URL seen previously, seen below. From here, you can download, upload, and manage the data however you need.

• https://<companyname>-my.sharepoint.com/personal/username_companyname_com

Remove Permissions

At this point, when the work is done, revoke your permissions to lock-down the OneDrive data once again by running the following command:

Set-SPOUser `
-Site "https://<companyname>-my.sharepoint.com/personal/username_companyname_com" `
-LoginName "i:0#.f|membership|admin@companyname.com" `
-IsSiteCollectionAdmin $false
