Author: Siluvia Last Modified: 2025-04-08

Normally, each email account in Outlook has its own Inbox folder. If you have created multiple email accounts in your Outlook, the corresponding Inboxes will be created at the same time. Have you ever tried to categorize the emails by message type and merge all the same type emails from inboxes across email accounts in Outlook? Here we introduce the "Merge Inboxes" feature of "Kutools for Outlook" to quickly merge Inbox folders from different accounts in Outlook.
