- Will other users know that I am not available?
It is not possible to send Out of Office messages in reply to Comments from other users.
The nearest thing is Approval Delegation, which can be used when an Approver leaves the office. It will send a one-time message to the person they are delegating their Requests to.
Other users who send Requests to the user who is away will be able to see that their Requests are being delegated, which can serve as an indication that they are out of the office.
