I guess your tasklist should be stored on the mailserver. So you should be
able to view and print it from any computer - new or old - by connecting to
the same mailbox than before...
However if you used a locally saved pst file, you will have to recover it
from the harddisk of the replaced computer and connect to it via the datafile
management tool.
If you don't have the harddisk anymore,well then i guess you lost your
tasklist
