Delegated mailbox?

[jasoncrcsd]

We have some delegated mailboxes, when a user is accessing a delegated mailbox if they send out email it comes from that mailbox but says near the address something like "sent on behalf of" is there any way of getting a log for emails of which users have sent out emails from a delegated mailbox?

Investigation Tool, Gmail Log Events.

Add Condition, Delegate, Is not, non-existing@email.com (you can write whatever here).

It will then list all messages that has a delegate, which isn't the one you listed above.

So, it'll skip emails that does not have a value in Delegate.
