Found this activity on one of our users "Create Item (Impersonated)" in Exchange Online. Been looking for a description for this but this is what I found:
Is this caused by Mailbox Delegation in Exchange Online? If yes what activity triggered this?
Would like to know a much detailed description for this activity.
