How to bulk remove contacts from distribution group and also from exchange online?

Question

Hi,

I was able to bulk insert from a CSV into Exchange Online using this script:
Import-Csv .\ExternalContacts.csv|%{New-MailContact -Name $.ExternalEmailAddress -DisplayName $.Name -ExternalEmailAddress $.ExternalEmailAddress -FirstName $.FirstName -LastName $_.LastName}

I was also able to bulk insert contacts into a distribution group using this script:
Import-CSV .\ExternalContacts.csv | % { Add-DistributionGroupMember DG -Member $_.ExternalEmailAddress }

I need code to bulk remove from an exchange group:

Then Bulk Delete from exchange online:

Would you please help me with this task?
Thank you

Hello @rntongoo

To discover users in group:

Get-ADUser -Filter * -SearchBase "ou=testou,dc=iammred,dc=net" -properties * | ft displayname, emailaddress  

To remove malboxes (format: Identity, EmailAddress):

Import-Csv "F:\Users.csv"  | foreach { Remove-Mailbox -Identity $_.Identity }  

Hope this helps with your query,
