# Connecting your calendar

42min works best when it can see your calendar. Once a calendar is connected, 42min
hides time slots when you're already busy, adds every new booking to your calendar
automatically, and — for the right event types — generates a video link. You connect a
calendar from [**Availability → Calendar**](/360/availability?tab=calendar). Both
**Google Calendar** and **Microsoft / Outlook** are supported, and you can connect more
than one account.

## What it does

- **Reading busy times** — 42min checks the calendars you mark for conflict checks and
  removes those times from your booking pages, so you don't get double-booked.
- **Writing events back** — when someone books, 42min creates the event on the calendar
  you've set as the write target; the invitee gets a calendar invite.
- **Video links** — for event types whose meeting type is Google Meet or Microsoft
  Teams, 42min adds a fresh conference link per booking (see
  [Conferencing](#conferencing-google-meet-and-microsoft-teams) below).
- **Multiple accounts** — connect, say, your work *and* personal accounts (Google,
  Microsoft, or both), and choose per calendar whether it's used for conflict checks,
  for writing new events, or just shown for reference.

## How to do it

1. Open [**Availability → Calendar**](/360/availability?tab=calendar).
2. Click **Add Calendar** and choose your provider — **Google** or **Microsoft /
   Outlook** — then sign in and grant 42min access to see and edit your calendar.
3. Back in 42min, pick which of that account's calendars **check for conflicts**
   (usually your main one) and which one new bookings are **written to**.
4. Repeat for any other accounts you want connected.

For the per-provider details, see [Google Calendar](/help/integrations/google-calendar)
and [Microsoft / Outlook](/help/integrations/microsoft-outlook).

<Callout type="tip">
Have separate "work" and "personal" accounts? Connect both and turn on conflict
checking for each — 42min then treats a personal-calendar event (a dentist appointment,
school pickup) as a busy block too, so a work call can't be booked over it.
</Callout>

## Conferencing (Google Meet and Microsoft Teams)

Video links aren't a separate connection — they ride on your calendar connection and
are switched on per event type:

- **Google Meet** — on the event type's **General** tab, set **Meeting Type** to
  *Google Meet*. Needs a connected **Google** account. See
  [Google Meet](/help/integrations/google-meet).
- **Microsoft Teams** — set **Meeting Type** to *Microsoft Teams*. Needs a connected
  **Microsoft** account. See [Microsoft Teams](/help/integrations/microsoft-teams).
- Other meeting types — phone, in person, custom URL, "ask the invitee" — don't
  generate a video link.

So a Google user picks Google Meet on their event types; a Microsoft user picks
Microsoft Teams; the link is created through whichever account is connected.

## Common issues

- **Connected, but slots are still wrong.** The *account* is connected, but the
  *calendar* holding your events isn't ticked for conflict checks — fix that on the
  Calendar tab. (Connecting an account is not the same as choosing which of its
  calendars to check.)
- **Bookings aren't landing on my calendar.** Pick a calendar as the **write target** —
  without one, 42min has nowhere to create the event.
- **No Google Meet / Teams link in the confirmation.** The event type's meeting type
  must be Google Meet (or Microsoft Teams) *and* you must have a connected Google (or
  Microsoft) account — both are required, and they must match.
- **Personal vs work account.** Connect the account whose calendar actually holds your
  meetings — a personal account with an empty calendar won't catch any conflicts. For
  Microsoft, this can also mean a personal (`outlook.com`) account vs an organization
  (work/school) account; connect the one you actually use.
- **Access revoked.** If you remove 42min from your Google or Microsoft security
  settings, the connection goes stale and conflict checking stops — reconnect from
  Availability → Calendar.
- **Wrong provider's conferencing.** If you're on Microsoft, don't set event types to
  Google Meet (and vice versa) — use the option that matches your connected account, or
  bookings will come out with no working video link.
