UniSent COM Add-in for Microsoft Outlook
E-mail Us
Updated: 19-October-2015
Other tools for shared mailboxes:

Suppose that Microsoft® Outlook® user John Doe has access to his personal mailbox and to the additional mailboxes (usually "Info" <>, "Sales" <> etc) on Exchange server. When he replies to or forwards from these mailboxes the message goes into his primary mailbox Sent items folder.
This utility ensures that the message sent with the second mailbox's From address stay in the mailbox that it originated from (i.e. the sent message goes to Sent Items folder of the mailbox the item was sent from).
Also you can easily see who was the original author of the message.
