If you’re like many business professionals, Microsoft Outlook is your daily companion. You rely on the calendar to help manage your busy schedule and keep track of your appointments. But is it working as hard as you are?

With client appointments, team meetings, and a constant flow of tasks, your calendar needs to be as organized and efficient as you are. Appointment reminders can help you streamline how you communicate with clients about their upcoming visits and keep your day-to-day schedule on track.

Outlook offers valuable tools for alerting clients about upcoming appointments, such as email reminders and popup desktop notifications. But if you want to add SMS reminders to your client communication strategy, you’ll also need to add Microsoft Bookings and Teams into the mix.

In this article, we’ll compare the process of creating appointment reminders in Microsoft 365 versus setting up fully customizable SMS, email, and call reminders with Apptoto. No matter which approach you choose, you’ll learn how to optimize your scheduling strategy and make your Outlook calendar work as efficiently as you do.

Setting Up Outlook Appointment Reminders in Microsoft

First things first: Can you send text message reminders for appointments directly from your Outlook Calendar? The short answer is no. If you only have an Outlook email and calendar, you cannot send text message reminders to your event invitees. However, you can add one desktop notification for yourself and up to five email reminders for you and your client.

Then, how do you send appointment reminders via text message for your Outlook Calendar events? 1) Use a third-party appointment reminder and scheduling solution such as Apptoto. 2) Send text messages using Microsoft 365, Microsoft Bookings, and Teams Premium.

Getting started:

1. Sign up for Microsoft 365 Business Basic (or higher)

2. Sign up for Microsoft Teams Premium

3. Sign into Microsoft 365 and navigate to the Apps tab.

4. Add the Bookings App, then navigate to Microsoft Bookings.

5. Create a shared booking page (or have your Administrator do so)

6. Fill out the four-step process to create a new booking page:

  • Fill out your booking page name, business type, and hours
Set up general Microsoft booking page information about your business
  • Link team members’ calendars to the booking page
Add staff members to your Microsoft booking page availability
  • Set up an appointment/service type and update duration/scheduling settings
Add services to your Microsoft booking page
  • Choose who can book appointments (anyone, team members, or no self-service)
Determine who is allowed to book an appointment using your Microsoft booking page

7. Click on the newly created booking page. From there, you can edit 20+ additional settings for your booking page, including appearance, access controls, consent policies, team member schedules, business information, and integrations.

Why Use Outlook SMS Reminders in Addition to Other Reminders?

SMS reminders offer a more immediate and personal way to ensure clients remember their appointments than email. Additionally, you may want to consider integrating SMS reminders with your Outlook calendar because:

  • Higher Open Rates: SMS messages have an open rate of 98%, making them far more effective than emails, which average around 20%.
  • Immediate Attention: On average, people open SMS messages within three minutes of receipt, ensuring your reminder is seen almost instantly.
  • Higher Customer Satisfaction: Personalizing SMS appointment reminders to include the client’s unique appointment details along with interactive confirmation options (such as links or reply “1” to confirm, “2” to cancel) helps increase customer responses and engagement. Plus, two-way business text messaging helps you resolve scheduling questions or concerns quickly!

Maximizing Your Appointment Reminder Effectiveness

To truly get the most out of all of your appointment reminders, consider these advanced tips:

Reminder Timing: Send reminders when your clients or patients are most likely to engage and respond. Apptoto analyzed thousands of appointment reminders to determine the best times to send email reminders (5 A.M.), phone reminders (3:00 P.M.), and SMS text reminders (6:00 P.M.).

Leveraging CRM Integrations: Integrate tools like Salesforce or other industry-specific CRMs with your reminder solution. Utilize your business’s wealth of client information to personalize client communication further and increase engagement.

Automation and Customization: Set up different reminder sequences depending on the appointment type. For example, specific medical procedures may require multiple reminders, while a single reminder might suffice for a routine check-up. (Bonus: For healthcare providers, it’s crucial to ensure your reminder solution is HIPAA-compliant)

Data Privacy and Compliance: Ensure you’ve collected consent to send reminders to your clients or patients about appointments, especially SMS messages. This is particularly important when handling sensitive customer data.

Apptoto’s integration with Outlook eliminates the need for manual event updates and reduces the risk of miscommunication or double bookings. It also means that any appointments added to your Outlook Calendar are automatically opted into receiving appointment reminders so long as they fall under one of your messaging sequences/rules.
