Prerequisites

Have a Google account or a Microsoft account ready. If you need one, create a Google account or create a Microsoft account before you start.

Connect Google Calendar

Why Google Calendar

Your appointments live there. It is simple to use, widely adopted across the internet, fast, and reliable. Connecting it gives CalendarApp a clear view of your schedule and a trusted place to save new bookings.

How to connect

1. On the connect screen, select Google and click Next to authorize your calendar.
2. In the pop-up window, choose the Google account to connect and continue.
3. Review the permissions and click Continue.
4. You will be redirected back to CalendarApp automatically. That’s it.

Connect Outlook Calendar

Why Outlook Calendar

Your appointments are already there, and Outlook is dependable and business ready. Connecting it lets CalendarApp read your schedule and place new bookings without changing how you work today.

How to connect

1. In CalendarApp, choose Outlook Calendar and click Connect.
2. Sign in with your Microsoft account in the pop-up window.
3. Grant the requested permissions so CalendarApp can read calendars and create events.
4. You will be redirected back to CalendarApp automatically.

Troubleshooting

• Permissions not granted or revoked — return to your Google Account or Microsoft account settings to re-grant access, then reconnect in CalendarApp.
• Wrong account appears — if several accounts are signed in, choose the correct one in the consent window or sign out of others and try again.
• Time zone mismatch — confirm your time zone in CalendarApp and in your connected calendar so booked times match.
• Pop-up blocked — allow pop-ups for your browser session and try again, or use a private window.
