Save Mail in Sent Items of Shared Mailbox Using Send As

How to save a copy of Send As emails to Sent Items with Easy365Manager

Granting a user Send As permissions to a mailbox will allow the user to send emails posing as that mailbox.

This is useful, e.g., if an assistant needs to send out emails for a manager or if multiple users need to send out emails from a shared mailbox, e.g., to perform customer support.

However, by default, any email sent using Send As permissions will only appear in the sent items folder of the actual sender – not in the sent items of the mailbox it was sent as.

This article will show you how to fix this.
