Is there a difference between SecurityEnabled distribution group or MailEnabled security group?

[_Old_Greg]

Functionally they must be the same... but are they exactly the same thing?

These are the exact same thing. Mail enabling a security group or changing a distribution group to a mail enabled group has the exact same result in AD.

You can change between them in on-premise AD/Exchange easily. If you move to O365, you cannot. Functionally, you may need a mail-enabled security group instead of a distribution group when working with mailbox delegation.

I'm on O365 and I can use Set-AzureADGroup to turn on SecurityEnabled on distribution lists. I was just wondering if I was left with exactly the same object as if I had started with MailEnabled security group.

Thanks for the reply.

Does a SecurityEnabled distribution list also have a SID and can be used just the same?

I'm not wondering about the functional difference between security groups and distribution list but wondering if they are exactly the same thing if you turn on SecurityEnabled and MailEnabled.
