Hope this may help as I had a similar issue when my Hard Drive died.
Prior to the drive crashing I copied all my data documents onto a external drive, so no problem there.
But what I was missing were all my emails from Mozilla Thunderbird. Luckily I also copied over the contents of the hidden folder User/Application Data - Local, Local Low, and Roaming. (To show hidden folders go to Windows Explorer, folder view, and click "show hidden folders").
If you can access that folder you'll be surprised to see what you can find! If you can access this folder from your old drive, simply copy it over (good idea to put it into a folder and name it, for example, old application data) and then click on all the folders there to see what you can recover.
Thunderbird emails are located in Roaming/Thunderbird/Mail. To copy the emails back over to your new hard drive, find the same folder on your new drive and simply drag the .msi and corresponding files over to your new drive into that folder where your new profile has been created. For example, amazon and amazon.msi will recreate your amazon folder and your amazon email. Not too sure of the procedure for Outlook, but if you search the net I'm sure you will find an answer.
Good luck. Ziggy...
