Connect Outlook Calendar to Sparkforge: Setup Guide

By Sparkforge Support Team ·Last reviewed May 3, 2026

Connect a Microsoft 365 or Outlook.com account in Sparkforge under Settings > Calendars > Connections. Once linked, Outlook events block your Sparkforge availability and bookings can sync back.

Connecting Outlook to Sparkforge keeps your real availability accurate. Bookings made in Sparkforge can write back to Outlook, and Outlook events show as busy time so clients can't book over them.

Connect the same Outlook account across multiple sub-accounts
Connect more than one Outlook account per user

Prerequisites

Fixing a deleted Outlook calendar

Limits

Outlook integration does not work with event calendars — event calendars only support Google. Disconnecting Outlook stops availability and event data from flowing in either direction, which will break calendar-based scheduling that depends on it.
