Undo Veeam O365 User permissions

[steffennw]

Hey there,

one of our admins tried Veeam365 Backup with his personal AdminAccount.
Now he is owner/member of all sharepoint sites and personal onedrives.
Is there a way to undo this??

Thank you!

Hi Steffen

Have you tried native SharePoint Online Powershell Commands in Office 365 to remove this Admin Account from all sites?

For Sharepoint Sites, I believe you can use commands like Set-SPOUser or Remove-SPOUser:

Hi Fabian,

and what about the personal one drive accounts of all employees?

Thanks, Steffen

OneDrive Sites are just personal SPO sites. The same command will work:

Code: Select all

#List all SPO Sites and Personal Sites
Get-SPOSite -IncludePersonalSite 1

#Check current Owners
Get-SPOUser -site https://*********-my.sharepoint.com/personal/username_tenant_onmicrosoft_com | Select LoginName,IsSiteAdmin | Where-Object {$_.IsSiteAdmin -eq 'True'}

#Remove Owner
Set-SPOUser -Site https://*********-my.sharepoint.com/personal/username_tenant_onmicrosoft_com -LoginName firstname.lastname@domain.tld $false -ErrorAction SilentlyContinue
