Accessing Attachments that are blocked by Outlook

A user had an issue whereby she was unable to access attachments in migrated messages. Upon opening a message with attachments, Outlook displayed a banner that stated that the 'potentially harmful' attachments had been blocked. By right-clicking the message and scrolling down to 'Attachments', Outlook displayed the path to the location in which the attachment was stored. In this instance, the path was:
C:\Program Files\Qualcomm\Eudora\Attach
All of the user's attachments from her previous email client are stored in this folder.
