Searching for attachments in Outlook

If you're looking for attachments in Outlook which contain a particular string in their file name such as a bates number prefix (e.g., the XYZ in XYZ0000000100), you can run a specialized search in the box above and to the right of the table listing email messages. [or just press CTRL + E] Enter the search in this format:

Attachments: "XYZ"

Such a search will pull up any attachments where the string "XYZ" appears in the file name - whether at the beginning, somewhere in the middle, or at the end.
