Outlook has a feature called Search Folder, which filters mails according to the criteria you set. You no longer have to manually search for a certain set of mails; instead, just access the Search Folder by clicking on it in the Navigation pane. To create a Search Folder, right-click on the Search Folders icon in the left pane. Click New Search Folder. Scroll down and select the Create a custom Search Folder option, and click Choose. Start by giving a name to the Search Folder. Click on the Criteria button to add keywords. Enter the necessary details and click OK. Click OK twice and the new Search Folder will be created.
