If you are investigating an issue that involves a deleted item or an item in the current active mailbox, select the mailbox by double-clicking the email address that corresponds to the primary mailbox on the account.
- Expand Root - Mailbox, and then expand IPM_SUBTREE if it is present. (If IPM_SUBTREE is not present, look for the Top of Information Store folder.) Under IPM_SUBTREE (or in the Top of Information Store folder), the folder hierarchy is displayed just as it appears in Outlook.
- Locate the folder that contains the item that you want to investigate, and then double-click that folder.
- You see a split view. The items in the folder (such as email messages, calendar items, notes, and so on) are displayed on the top. Browse through the items, and then click the item that you want to investigate. The bottom view shows the properties of the selected item.
Note To make it easier to find items, you can sort the lists by clicking the column headings.
