An iCloud Calendar Invite is a digital event invitation sent through Apple’s iCloud Calendar service. Users can create events and invite others by email or Apple ID, allowing recipients to add the event to their own calendars with a single click. While designed for convenience and collaboration, iCloud Calendar Invites can sometimes be exploited by scammers to send unwanted or fraudulent event notifications that appear legitimate, potentially leading to phishing or spam. Users should be cautious when accepting invites from unknown senders.
