Arctera Personal Archive lets you search message attachments to locate archived messages that contain a specific attachment or a supported attachment type.
Use Query Search to search for a specific attachment by entering its file name. Use Advanced Search to search attachment content or find messages that contain a particular attachment type. When searching by attachment type, select Has Attachment, and then specify the required type in the Attachment Type field.
Note: Password-protected and encrypted attachments are not included in searches.
