How to quickly search all emails by selected email domain in Outlook?

Author Siluvia Last modified

When handling a large volume of emails in Outlook, finding all messages from a specific email domain can be a time-consuming task. Instead of manually scanning through your inbox, Outlook provides a built-in Search feature that allows you to filter emails. However, for a faster and more efficient approach, Kutools for Outlook offers a one-click solution to instantly search all emails from a particular sender’s domain. This guide will show you two methods:

Method 1: Manually Search All Emails by Email Domain in Outlook (Basic & Manual)

Method 2: One-Click to Search All Emails by Sender Domain with Kutools for Outlook 👍 (Fast & Automated)


Method 1: Manually Search All Emails by Email Domain in Outlook

If you prefer to search for all emails from a specific domain manually, follow these steps:

1. Click inside the Search field in Outlook to activate the Search Tools tab.

2. In the search bar, type the domain name (e.g., example.com) into the search bar.

⚡ Tip: To refine your search, use the Scope options under the Search tab to filter emails within a specific folder, mailbox, or across all mailboxes.

Limitations of the Manual Search Method:

  • ❌ Manual Input Required: You must type the domain every time you search.
  • ❌ Prone to Errors: A simple typo can lead to inaccurate results.
  • ❌ No One-Click Execution: Lacks a built-in one-click filter for domains.
