After updating email, notifications no longer showing in "Sent Items" folder

[Mackenzie R]

We recently updated the email address that we send and receive from in Service Desk. Since updating the outgoing mail and incoming mail address and server information, the email notifications sent out Service Desk are not showing up in the "Sent Items" folder in outlook. 

Is there something I missed when updating the emails?

Did you ever manage to find a resolution to this? I've experienced exactly the same issue today.
