If you use Outlook to help manage and organize your life (and why wouldn’t you?), you’re probably well aware of the various rules, filters and notification options it has. But did you know that if you use Office 365 that you can set it up so that you can receive text messages sent to your phone for calendar or email notifications? Here’s how to set it up.
First, log into your Office 365 Portal.
After logging in, if Outlook Web App isn’t automatically loaded, click on the 3×3 Grid Icon 
in the upper left portion of the page and select “Mail.”
After you get logged in, click on the gear icon in the upper right and click on “Calendar” under “Your App Settings.”
After opening the options dialog, click on the “Text messages notification” option. If you haven’t setup your cell phone for notifications before (if you had, you wouldn’t be reading this), then click on “Set up notifications”
After clicking on the “Set up notifications” link, click on the “Set up text messaging” link.
The next window will ask you for your country and your mobile carrier. Select both and click “Next.” Note: This feature is currently only support by AT&T, Sprint, T-Mobile and Verizon. If you use a different carrier, this services will not work for you.
Input your phone number on the next screen and hit “Next.”
Microsoft will then send you a text message with a six-digit verification code. Insert that code in the next screen and hit “Finish.”
After you hit finish, you’ll see a screen where you can setup rules and notifications for your calendar notifications, notification rules for emails and more. Click on either of those options to setup rules on how you would like to be notified, based on your individual needs.
