Configuring Outlook Rules to Identify and Manage External Emails

This article outlines a step-by-step approach to creating mail rules in Outlook for managing emails received from external senders. By configuring these rules, external emails can be automatically routed to a specific folder or deleted, while emails from the organization’s domain are excluded – helping keep the inbox organized and clutter-free.

1.     To create a new folder in Outlook, follow these steps:

a.       In the Folder pane on the left, locate the mailbox where the folder should be created (for example, under Inbox) and click on the ellipsis (three dots) next to the mailbox.
