Outlook allows several key productivity features that Thunderbird currently lacks. These include unified categories and tags across emails, events, contacts, and tasks; customizable views that consolidate all item types by category; the ability to drag emails or contacts directly into the calendar or task list to create new associated items; and precise control over reminder times for every item type. Without these integrated capabilities, Thunderbird cannot fully replicate Outlook’s seamless and interconnected workflow.
