Defining AI Powered Experiences in Microsoft Outlook

The integration of artificial intelligence (AI) into design has revolutionized the way we approach design. This project complies set of initiatives related to Agents, Pesonalization, Productivity and learnings from Microsoft Outlook.

Reinventing the Outlook experience

Today the limitation of Outlook is that the value that customers get out is proportional to the energy they put in. The promise of AI is that we can decouple the relationship between value -- goal accomplishment, and inputs -- customer energy.


My Role and Impact

At Outlook IDC, I currently lead the end-to-end design of Outlook experiences across mobile and desktop platforms, serving 700M+ monthly active users globally. I have contributed to key Copilot-led AI features in Outlook, now adopted by 9M+ monthly active users in total, scaling productivity and personalization at enterprise level.


In addition, as design lead I manage a team of three designers, I partner on cross-geo initiatives to define future-facing Copilot experiences and strategic AI-powered tools that influence multi-million user adoption and Microsoft’s enterprise productivity roadmap.

Paving way to 0 - 1 AI experiences in Outlook

Digital Personalization
Digital Personalization

The advent of personal computers introduced a new realm for customization. Users delighted in changing wallpapers, customizing icons, and applying unique skins to media players, fostering a sense of ownership and individuality in the digital space. However, this freedom also highlighted the need for thoughtful design, as excessive customization could lead to usability challenges.


Dark Mode

A notable milestone in digital personalization was the introduction of dark mode in Android 10 and iOS 13. This feature seamlessly blended form and function: offering aesthetic appeal, reducing eye strain, and conserving battery life on OLED screens. It exemplified how technology, when thoughtfully designed, can cater to user preferences while enhancing functionality.

AI: The New Frontier in Personalized Experiences
The Role of AI in Personalization

Implicit customization—where AI learns from user behavior to make automatic adjustments—is becoming the standard. Think of Netflix's recommendation engine or Spotify's personalized playlists. These AI-driven experiences optimize for relevance, engagement, and user delight, surfacing the right content at the right time.


Today, artificial intelligence is revolutionizing personalization, enabling experiences that are not only tailored but also adaptive and context-aware. AI analyzes user behavior, preferences, and environmental factors to deliver bespoke interactions.

Responsible AI by Design

As AI becomes increasingly integrated into our designs, responsible AI practices must be a priority. Designers and developers need to ensure AI-driven solutions are:

  • Accessible to all users
  • Free from bias and inclusive
  • Designed with minimal complexity to prevent cognitive overload
  • Secure and privacy-focused, respecting user data
Key Takeaways
Video cover

Ensure Consistency & Maintain Core Branding

Maintain core branding even in customized themes. For example, if your app's identity is blue, keep it blue even in a red-themed UI.


Set Guardrails: Evaluate for Bias, Minimize Overload

Set clear constraints for theming, minimize unnecessary choices, and ensure equitable design to avoid bias.


Gradient of Customization – Designing for All Users

Offer a spectrum of options: casual users get simplicity, while power users can tweak more without overwhelming the experience.


Safe Defaults Are Essential

Many users stick with the default theme, so make it great. Choose default which brings the best of your app.


Design Token System

AUse a single source of truth (e.g., Figma tokens) to ensure consistency across designers and developers.


Accessibility is not an after thought

Personalized themes should never compromise usability. Warn users if their color choices reduce contrast


Privacy and Consent Matters

Privacy implications, such as location-based access, and ensure transparency with users.


Context & Opt-Out Flexibility

Users should be able to reset to default and undo changes easily. Personalization should be an enhancement, not a burden.


Performance & UX Balance

Theming should never slow down or interfere with content personalization. Optimize for speed and usability.


Outlook Personalization and Theming

Presenting how personalization lies at the heart of the Outlook experience—where expression, belonging, inclusivity, and adaptability come together to create a product that truly feels like yours.

Outlook Theming
Event Based Theming

During the Cricket T20 World Cup and Olympics we introduced event based theming for our users. By choosing themes aligned with their favorite teams, fostering a more immersive and personalized experience. Notably, the time required to go from asset creation to production-ready visuals was reduced to one-fourth, greatly accelerating delivery. Key learnings from this initiative included addressing AI hallucinations, managing dark and light mode variations, and ensuring an accessible color palette.​

Dynamic personalized theming with Copilot

In November 2024, Microsoft introduced "Themes by Copilot" in Outlook, an AI-powered feature that allows users to create personalized themes reflecting their preferences and style.

Personalization is all about respect for the user.

It says, 'You are unique, and this product recognizes that and enables you.'

A Perfect Partnership
AI as an Enabler

Our journey into generative AI revealed its remarkable capacity to augment human creativity. By integrating AI into our workflow, we reduced the time from asset creation to production-ready outputs by 75%, allowing us to explore a broader array of creative variations.


You as an Enabler

While working with AI, as we harness AI's potential, it is imperative to uphold our responsibility toward users. Establishing clear guidelines and guardrails ensures that AI-driven designs are equitable and inclusive, aligning with ethical standards.


Embracing the Synergy of AI and Human Creativity

At the intersection of artificial intelligence and human ingenuity lies an unprecedented opportunity to craft personalized, contextual, and adaptive experiences. This collaboration promises a future where technology not only complements but also amplifies individual preferences and desires, leading to richer and more resonant user experiences.

People Network

Our mission is to become network powered daily habit app for content centric mobile workflows​. As the mordern apps are moving towards People centeric Network, to increase engagement and retention in the app. People centric principles can increase relatitbility with the app. Evaluate, design responsibly and examine factors such as FOMO, Social Validation, Self Disclosure, creators economy aspect of network.


Sarnoff's Law
V=n

The value of the network (V) increases in direct proportion to the size of the network (n).


Metcalfe's Law
V=n2

The value of the network increases to the square of the number of users in the network.


Reed's Law
V=2n

Networks may grow proportionally to the network size but there are forming groups that scale faster in value than others (because of influence or interconnectedness).

Business Need

Creating an engagement loop: Acquisition, Activation, Retention, Referral, Revenue, where new users are brought to the funnel, inactive users are revived, and active users are retained, is one of the few directions for this work effort. Therefore, keeping a view of different kind of users namely Churn (inactive), retained and new.

Retention

Of the total users only 31% is retained.

Share Engagement

Consumer and academic engages the most.
