The Microsoft Outlook SMS Add-in adds SMS sending functionality to Microsoft Outlook 2003 and Microsoft Outlook 2007. Before you begin to rejoice thinking of all the money that you can save you should notice that the add-in only works with a cell phone connected to the computer system. That is a bit of a turn off for many users but it might still appeal to some who prefer to use a real keyboard when writing SMS.
The process of sending SMS in Microsoft Outlook has been designed to resemble that of sending emails in the email client. This means that SMS can be saved as drafts and printed as well as send out to the recipient. The sent items are extended by a SMS subfolder that contains all the SMS messages that have been sent out from Microsoft Outlook.
The major advantage of the Microsoft Outlook SMS Add-in is the use of a computer keyboard to type the message. Other factors include the ability to copy and paste text, the use of proof reading tools in Outlook and to lookup and resolve phone numbers to existing Microsoft Outlook contacts.
The Microsoft Outlook SMS Add-in will be automatically available in its own toolbar after installation. It does have a few restrictions though, the most notable are that it can only send out normal SMS message, and that it cannot receive messages.
Update: Please note that the add-in can only be installed if you are running Outlook 2003 or 2007, it won't work when you run Outlook 2010 or 2013.
It needs to be noted that you can't use the Outlook add-in to receive SMS message, only to send them to recipients. While that's not a big issue per se, it means that you may have to juggle between your phone and Outlook at times to communicate with a contact.
