Did you know it is simple to send SMS text messages from Outlook? If you read the Outlook help file on this topic your head will start spinning before you get to the really simple instructions you need to make this work. After reading about Exchange server settings and Windows Mobile devices 6.5 or higher you will be apt to give up and think it is only one of those works-for-MS-fanboys-but-not-for-me things.
Not so. All you really need to know is the text message email address for the party you want to send the text message to, along with their phone number, of course. Then you simply address email with the phone-number@TextMessageEmailAddress.
The most common providers will be AT&T, Verizon, T-Mobile, and Sprint. Here are the email addresses for those message providers:
A simple Google search will find the addresses of the other smaller providers.
Now, be careful. The party you send the message to may be charged, depending on their plan.
