Dear Team, Greetings for the day! We need to add members to "sender inside and outside organisation" in the mail enabled security group via powershell as we are unable to do so via gui interface. Please suggest with screenshot. Assuming ******@contoso.com is a mail enabled security group and ******@contoso.com is an intended recipient. Your quick response will be highly appreciated.

Hi @Gurudas ,
From the description, seems like you are trying to modify the delivery management settings for the mail-enabled security group, right?
If this is true, you can run the command below:
Set-DistributionGroup -Identity "Dl-finance-all" -RequireSenderAuthenticationEnabled $false -AcceptMessagesOnlyFrom @{Add="******@contoso.com"}
Reference: Set-DistributionGroup.
Actually, according to this official document, this can also be completed in the Exchange admin center. Select the group in EAC, click the Settings tab on the details pane, click "Edit delivery management":
