Microsoft Outlook 2021 – Retail Activation Key (1 PC)

Microsoft Outlook 2021 is the one-off purchase edition of Microsoft's e-mail client, sold on its own rather than as part of the Office suite, for 1 PC. It combines e-mail, calendar, contacts and tasks in a locally installed application, so you can read your stored messages even when you are offline.

Main capabilities

• Several accounts at once: Exchange, Microsoft 365, IMAP and POP, with rules, categories and search folders.
• Calendar: meetings, recurrences, invitations, shared calendars and overlay view.
• Contacts: a detailed address book and distribution groups.
• Tasks and follow-up: reminders, follow-up flags and a built-in task list.
• Quick search: the search bar at the top of the window finds messages, attachments and contacts in a few keystrokes.
• Local .pst archives: keep older messages on your own disk.

New in the 2021 version

The interface is simpler, with search at the top of the window. You also get built-in message translation, suggested replies, dark mode that extends to the body of messages, and noticeably better performance at start-up and when syncing large mailboxes.

Paid once, not by subscription

You pay for this licence once and it does not expire. Unlike the Outlook that comes with Microsoft 365, it does not gain new features over time and does not include hosted mailbox space: you connect your own e-mail accounts.

System requirements

• Windows 10 or Windows 11
• 1.6 GHz dual-core processor and 4 GB of RAM
• 4 GB of available disk space

Activation and delivery

Install Outlook 2021, open it and enter the key under File › Office Account; activation is done online. Odin Key sends the key by e-mail within 24 hours of payment, with the activation steps. An official invoice is included, and support is available in English by e-mail and live chat.
