Email remains a cornerstone of daily professional communication, yet it also consumes a significant portion of our working hours. Microsoft 365 Copilot is poised to shift that balance by embedding generative AI directly into Outlook, turning tedious email tasks into automated, intelligent workflows.

From summarising long email threads to drafting polished responses and scheduling meetings with a few natural language prompts, Copilot harnesses your Microsoft 365 data to supercharge productivity without leaving Outlook. This post explores 28 practical tasks you can try today with Microsoft 365 Copilot in Outlook — empowering you to work smarter, not harder.

We’ll walk through how Copilot leverages your organizational email, calendar, and files to automate complex multi-step email workflows, tone adjustments, and context-aware communications. Whether you’re catching up after time away or preparing for a critical meeting, these tasks showcase the practical AI assistant capabilities integrated seamlessly into Outlook.

How It Works: Exploring Core Outlook Copilot Tasks

Summarising and Managing Email Conversations

To quickly digest long email threads, select an email conversation and invoke Copilot with a prompt such as:

Summarise the email conversation about the Microsoft 365 Copilot Adoption – Project Kick off project. List the team members involved and highlight any outstanding actions I need to be aware of in table format.

Copilot then scans the thread using organizational data, extracting participants, decisions, and action items — displayed in a clean summary or structured table right within Outlook.

Drafting and Editing Emails with AI Assistance

You can ask Copilot to draft polite follow-ups, concise reminders, or replies — for example:

Draft a polite follow-up email to Darren O’Malley suggesting one of the available 30‑minute Teams meeting slots for the week commencing 18 May.

This draft is inserted into your Outlook compose window, where you can tweak or use Copilot’s tone adjustment prompts, such as:

• "Rewrite this email to sound more friendly and conversational."
• "Make this email more concise without losing the key message."

Copilot updates the draft inline without overwriting your base content until you approve.

Scheduling and Calendar Integration

Simply prompt Copilot for available meeting slots between you and a colleague:

When is Andrew Doe available for a Teams call in the week commencing 18 May? Please suggest suitable 30‑minute slots.

Or use the "Schedule with Copilot" feature from within an email discussing a meeting to generate invites with agenda suggestions automatically.

Multi-Task Workflow with Copilot Cowork

The Frontier program’s Copilot Cowork agent introduces deeper automation, where Copilot can:

• Create and send emails autonomously with approval
• Manage calendar and meetings holistically
• Edit documents across Word, Excel, and PowerPoint
• Post updates to Teams channels
• Track and report workflow progress step-by-step

This agentic assistant can perform multi-step tasks while requiring user checkpoints, enabling complex workflows like monthly reports or executive briefings efficiently.

Voice Interaction for Hands-Free Productivity

Copilot voice (audio summary) enables auditory catch-up and interaction. For example, you might ask:

When is my next meeting with my manager?

And Copilot will respond verbally, allowing mobile workers or multitaskers to remain productive without screen interaction.
