Thanks so much for this , helped me out yesterday , one issue I did find was Duplicate group names due to the Get-AzureADGroup -SearchString , was picking up 365 Groups along with Distribution groups
Adding the below to Line 16 will filter these out ( only way I could determine 365 groups was using the SPO proxy address )
$List = $list | ?{$_.proxyaddresses -match ‘.*SPO.*’}
I also rewrote your script to copy help me Azure AD Security Groups
