UniSent COM Add-in for Microsoft Outlook

Suppose that Microsoft® Outlook® user John Doe has access to his personal mailbox and to the additional mailboxes (usually “Info” <[email protected]>, “Sales” <[email protected]> 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.

Current versions:    UniSent2007 ver    UniSent2010 ver

How it works

UniSent utility scans sender address of each sent message in the main mailbox Sent items folder and in case it matches the additional mailbox name moves the message to the appropriate Sent items folder.
