Office SMS


Send Text Messages From Outlook

Send and receive SMS directly from Microsoft Outlook just like email, using our Office SMS software.

*See notice below about upcoming changes—this does not affect Office 2007-2021 users at this time.

*Changes Coming to Microsoft Outlook:

Microsoft 365 will not be supporting COM add-ins on the newest version Outlook, meaning the current Red Oxygen Office SMS solution will not work with the update, or any other COM add-in you’re currently using.

But have no fear, while Red Oxygen puts the final touches on our new software solution you can continue using Office SMS on the classic version of Microsoft 365’s Outlook application (don’t toggle to the preview version) or the Office 2007- 2021 applications.

Red Oxygen is on top of it and will be unveiling our new software in the coming weeks—stay tuned.
