Lotus Notes had a feature called "Send & File" that allowed the sender to save a copy of the sent message in a folder other than the default "Sent Items" folder.
In order to "Send & File" messages in Microsoft Outlook, perform the following steps:
1. When composing the message, click the "Options" section on the ribbon.
2. Click the "Save Sent Item To" button, and choose other folder.
3. Choose the folder in which you would like to save the sent message.
Note: Outlook will only save one copy of a sent message. If you have Outlook configured to save all sent messages, and you use this option, the message will be in the folder you select and will not also appear in Sent Items.
