Once you Sign Up with SMSOfficer, you’ll find a Text Message command which is available
under the New drop down. Important: use the international format for your recipient
number (e.g. +14155708928 for US/Canada or +447949149888 for UK)
* If you can’t find the Text Message command, please close your Outlook, wait about
20-30 seconds and launch it again. Also, you may check if the OMS item is listed
under the Help->Disabled Items and enable it.
