Click the Settings button on the dialog to open the Options dialog to the Mail page. When you use Clean Up, a dialog box will remind you that redundant messages will be moved to the designated folder (unless you ticked the Don't show this message again box). Clean up Folder and Clean Up Folder & Subfolders commands are also on the Folder tab. Right click on any thread and choose Clean Up Conversation in the context menu or look for it on the Clean Up button in the Delete Group on the Home tab. In addition to Clean Up Folder, Outlook can also Clean Up Conversations, removing older messages in a thread that are quoted in newer messages. Change these settings in File, Options, Mail. If you didn't select a clean up folder, Outlook will use the Deleted Items folder.īy default, Outlook won't clean up categorized, flagged, or digitally signed messages.
Everything imported or downloaded later will have the same modified date. It's usually faster to use a ' duplicate remover utility', however, if the duplicates are due to importing or re-downloading messages, ' you can add the Modified date field to the view and sort by it'.
The Clean Up folder (and subfolder) commands will clean up all threads in a folder (and subfolders, if that option was selected), while clean up conversation will remove the older messages from the selected thread.Ĭlean Up will not remove duplicate messages.
