Microsoft Outlook and Exchange Calendar offer users a comprehensive solution for managing their emails, schedules, and tasks in a professional environment. OnceHub uses them to manage users’ availability and connections.

Our native connector makes light work of linking your Outlook/Exchange Calendar to our platform, instantly bringing on board all the calendar features that you and your team have come to rely on when planning their days on and off the job. From there on, our integration automates synchronization across both platforms.

Benefits of using OnceHub with Outlook/Exchange Calendar

Two-way calendar synchronization

OnceHub communicates with Outlook/Exchange Calendar in real time, automatically confirming your availability to meet. Appointments made through our system are, in turn, added to the calendar, and all information collected during the scheduling process is accessible from it.

Time and workload management

OnceHub has a large number of features to ensure you’re always the one in charge of your time. These include settings for the number, spacing, lead time, duration, and start time of meetings.

Realtime notifications

Automated reminders and follow-up messages via email or text message save time on administration and help reduce no-shows and other scheduling mishaps. You have full control over when, how, and to whom they are sent.

Canceling and rescheduling

Meetings can be canceled or rescheduled with ease, either through OnceHub or Outlook/Exchange Calendar. OnceHub automatically updates participants with a cancellation notice or new booking details.


OnceHub only displays what remains of the time slots that users have chosen to make themselves available for meetings on the system. Calendars themselves are never shared, so your free/busy patterns are never revealed to customers.

Secure OAuth connection

OnceHub uses the OAuth protocol to establish a secure connection with Outlook/Exchange Calendar, so users can connect without sharing their credentials with anyone.

Nice and simple

Scheduling appointments with OnceHub is quick, easy, and eliminates the tedious back and forth associated with finding a time that works for everyone. Now, meetings can be set up in seconds and start on time, with no initial technical set up required.

Outlook/Exchange Calendar integration through Zapier

OnceHub offers a native Outlook/Exchange Calendar connection for real-time calendar updates and a streamlined meeting lifecycle, but you can also choose to integrate using Zapier.
