Mainly through outlook desktop app and I have checked on Gmail console (we are using Google Aps for Mail hosting).

IMAP clients is configured outlook, although when checking on Gmail the headers are not showing the client IP.

No, I sent an email from different Gmail account and it included the client IP.

Thanks,

Dears,

I noticed that the "Received: from" part of the header contain an IPV6 IP for the email sent from outlook.com (as below), though other mail servers send it with  IPV4 details. is there a way to identify the IP ?

Hello, thank you for the reply, 

message analyzer also showing the IPV6 IP as below.

Dear Solar-Eclipse,

I already have those from the headers, but the issue I am not able to identify the sender real IP (public IP and location) using the IPV6 IP.
