# Update calendar and Slack permissions

Grant newly required calendar or Slack permissions without removing a healthy connection first.

When In Parallel needs an additional permission from a connected calendar or Slack account, the integration can show **Update available**. Use that action to repeat authorization and add the missing permission without disconnecting a healthy connection first.

## Update a calendar connection

1. Open your user menu and select **Settings** .
2. Open **Account → Connections** .
3. Under **Calendar** , find the connected Google Calendar or Outlook Calendar account.
4. If it shows **Update available** , select that action.
5. Complete the provider’s authorization flow and return to In Parallel.
6. Confirm that the integration shows **Connected** .

If no permission update is needed, the connected calendar shows **Disconnect** instead. Disconnect only when you intend to remove access or when a revoked or expired provider session cannot be recovered with the update flow.

## Update Slack permissions

Slack has two related connections:

- the Slack app installed for the Workspace;
- your personal Slack notification connection.

In **Settings → Account → Connections**, the main Slack button shows the most relevant available action. Additional actions appear in its menu.

- Select **Update available** to grant newly required permissions to the Workspace installation.
- Select **Update notifications** to refresh permissions for your personal Slack notification connection.

Complete the Slack authorization flow. Updating the Workspace installation in place preserves users’ personal Slack connections; uninstalling the app does not.

## When updating is not enough

**Update available** detects missing permission scopes. It does not detect every revoked or expired token. If an integration still fails and no update action appears:

1. note which account and provider are connected;
2. select **Disconnect** , **Disable notifications** , or **Uninstall** only after reading the confirmation;
3. reconnect the same provider;
4. check upcoming meetings and notification settings afterward.

Uninstalling the Slack app affects everyone using that Slack Workspace. Ask a Slack administrator to confirm the impact before removing it.
