Does anyone know if there's a way to delete SharePoint Online Profile Pictures programmatically?
For On Premise SharePoint, I'm managing this via this PowerShell Scripts:
# Convert string $objectSid to byte $byteSID
$sid = New-Object System.Security.Principal.SecurityIdentifier ($objectSid)
$byteSID = New-Object 'byte[]' $sid.BinaryLength
$sid.GetBinaryForm($byteSID, 0)
$site=new-object Microsoft.SharePoint.SPSite("http://onprem.sharepoint.local")
$serviceContext = Get-SPServiceContext $site
$upm = new-object Microsoft.Office.Server.UserProfiles.UserProfileManager($serviceContext)
$Userprofile = $upm.GetUserProfile($byteSID)
$Userprofile["PictureURL"].value=$null
$Userprofile.Commit()
These users does not have Exchange Online Mailboxes, so I cannot use Set-UserPhoto
I managed to upload photos using via this method, but I cannot remove the pictures once uploaded:
