Conversation view
The Conversation view is an alternative arrangement of messages grouped by subject. All the letters with the same subject appear together in your Inbox or another message folder under one conversation header.
When you receive a message that is part of a conversation (has the same subject), the entire discussion moves to the top of your Inbox, and the new message shows when you click the conversation header.
To turn on the Conversation view for the folder, do one of the following:
-
On the View tab, in the Messages group, select the Show as Conversations checkbox:
-
On the View tab, in the Current View drop-down list, select the Show as Conversation
item:
In the Outlook message dialog box, choose messages to group into conversations:
- This folder to show the Conversation view only for the current folder.
- All Mailboxes to show the Conversation view for all folders of all added accounts.
There are several useful settings that you can configure to work more effectively with conversations.
