Text Customers from Microsoft 365

*See notice below about upcoming changes.

Send SMS messages directly from your Microsoft 365 (formerly Office 365) Outlook interface, accessed through a browser.

  • Outgoing text messages are delivered to the mobile devices of recipients as SMS.
  • Incoming replies are delivered as emails to your inbox.

*Changes Coming to Outlook:

Microsoft 365 will not be supporting COM add-ins on the newest version Outlook, meaning the current Red Oxygen Office365 SMS solution will not work with the update.

While Red Oxygen puts the final touches on our new software solution you can continue using Office365 SMS on the classic version of Microsoft 365’s Outlook application (just don’t toggle to the preview version).

Red Oxygen will be unveiling our new add-in in the coming weeks—stay tuned.
