Get mailcontact if member of any group

It's funny coming across your own posts again.... I've had questions about how can this be completed for cloud only objects in Exchange Online? This should help and is much better than everything else I've seen ;) Stay safe out there! J   

$allcontacts = Get-MgContact -all -Property MemberOf -ExpandProperty MemberOf
$allcontactsingroup =  $allcontacts | ?{$_.memberof -ne $null}

#Print to Screen
$allcontactsingroup | FT DisplayName,MemberOf
 
#Export to CSV with some Funkyness (is that even a word?)
$allcontactsingroup | Select *, @{Name = 'MemberOfToString'; Expression = {$($_.MemberOf.id -join ',')}} | export-csv contactsingroup.csv
