AI Summarization for Outlook Emails
In today's fast-paced work environment, email communication is essential. Quickly extracting key information from emails can boost efficiency and prevent missing critical details.
For example:
- When receiving long emails, reading everything can take too much time. A quick summary helps you grasp the key points faster.
- When managing multiple emails related to a project, reading each one individually can be time-consuming and lead to missing key updates. Summarizing all related emails together provides a clear overview and improves efficiency.
This tutorial will guide you through using AI to summarize both single and multiple emails efficiently.
Single Email Summarization
Summarizing a single email is a common task, and most AI tools can handle it with ease. Below are two recommended methods:
Method 1: Online AI Solutions
There are many online AI tools available that can quickly summarize content. Here’s how to use one of the most popular tools, ChatGPT, as an example:
Step 1. Open the email in Outlook, select the text, and copy it (shortcuts: "Ctrl" + "C").
Step 2. Go to ChatGPT or a similar AI tool, paste the email content, and enter a prompt like "Summarize below content:". Then click the "Send" button .

The AI will generate a concise summary. Copy and use it as needed.
If you are not satisfied with the provided summary, you can add your requirements and request it to generate a new summary.
Pros & Cons
✔️Pros
- Most online AI tools are free to use.
- No need to install any software, can be used instantly.
❌Cons
- Manually copying and pasting every email can be tedious, especially for multiple emails..
- Potential privacy risks, as pasting email content into third-party AI tools may lead to data exposure.
