Outlook - Group Similar Emails is a simple configurable extension for the Chrome browser that enhances your Outlook email experience. Developed by Ian D Halverson, this free add-on falls under the Browsers category and specifically the Add-ons & Tools subcategory.

This extension visually hides emails with duplicate sender and subject in Outlook, making it easier to manage your inbox. It is important to note that this feature only works when the reading pane is disabled or placed at the bottom. By default, duplicate emails are determined based on identical content in the sender and subject columns, although this can be configured to suit your preference.

Outlook - Group Similar Emails offers several configuration options, allowing you to customize the extension according to your needs. It also modifies the subject of duplicate emails to display the total number of duplicates, giving you a clearer overview of your inbox. The extension runs its logic every 2 seconds, ensuring that it constantly updates to reflect any changes in your emails.

While this extension provides a convenient way to manage similar emails in Outlook, it is important to note that if you need to interact with or view the duplicates, you can easily toggle off the extension. Fixes and new versions may take some time to publish, so patience is appreciated. If you encounter any issues, the developer can be reached on Github.
