How to get all users exported from an AD AzureGroup listing their,email addresses?

VasilMichev Thanks for the reply,

$groups = Get-AzureADGroup -SearchString TeamOne
foreach ($group in $groups) { Get-AzureADGroupMember -ObjectId $group.ObjectId | select @{n="GroupName";e={$group.DisplayName}},DisplayName,UserPrincipalName Export-Csv -nti GetTestGroupMembers.csv
 }

I tried adding an export function to it like above but it seems i'm only getting the fist group on the list.
But i can see that you are looping through all the groups.
Am i missing something.

I need it to export all the groups in the list to the csv

Thanks in Advance
