The following step-by-step tutorial will help you create a search folder and group all messages that are older than your specified period.
2. In the New Search Folder dialog box, select and highlight the Old mail in the Select a search Folder: box. And then select an email account in the Search mail in drop-down box. See right screenshot: By default, it will group messages older than one week into the new created search folder. If this default condition “older than one week” meets your needs, please click the OK to finish the setting. If you want to modify the definition of old time, please go on to the following steps.
3. In the Customize search Folder: section, click the Choose button.
4. In the Old Mail dialog box, please definite the old time according to your needs. In our case, we enter 1 in the first box, and select the month(s) in the second box. That’s meaning it will group all messages older than 1 month.
5. Click the OK buttons in each dialog box. Then you will find a new search folder is created and added into the Navigation Pane, and the new folder’s name is based on your definition of old time.
