List of e-mail addresses in the organization to which external users can send e-mails.

New Contributor




I would like to export somehow list of e-mail addresses (GROUPS) which can be used by external users.

I know how to export all groups or users, but I need just those where option "allow external senders" is ticked.


Can someone help me please?

Thank you!

That's pretty easy to do with PowerShell, all you need to do is filter Groups by the RequireSenderAuthenticationEnabled property:


Get-UnifiedGroup | ? {$_.RequireSenderAuthenticationEnabled -eq $false}
