How can I find out which device we used for sending mail?

Question

We have 1 mailbox that used by some user from different device. Everyone used that mailbox for send mail. How can we make sure which device actually sent a specific mail?

Hi @Ibrahim Khalid ,
We can not directly determine which device sent the mail, but we can find the device that sent the mail through relevant information:
1.By the SourceContext field which reports the ClientType property for SUBMIT events in the message tracking logs :

2.By viewing the IP address of the device. You can easily find related devices by fixing and recording the IP address of the device. In addition, you can view the IIS log, which will also display the IP address of the client sending the request.
