Remove all groups on a user with Powershell;
# Get the correct mailbox
$mbx = ( Get-Mailbox UserPrincipalName )

# Process all DistributionGroups and if mailbox is member remove (with simple console output)
foreach ($group in Get-DistributionGroup -ResultSize unlimited) {
 if ((Get-DistributionGroupMember $group.identity | select -Expand distinguishedname) -contains $mbx.DistinguishedName){
  write-host "Removing user from" $group.name
  Remove-DistributionGroupMember $group.name -member $mbx.DistinguishedName -BypassSecurityGroupManagerCheck -confirm:$false
