Track E-mails after send it

Hi there,

I have had CRM Dynamics installed in my laptop for more than one year but I have never tracked any e-mail. Now I need to track everything and I would like to track all the mails from the past.

My questions are:

-Can I track e-mails sent in the past?

-Can I select all the past e-mails from the same sender and track all of them in once?

Thanks a lot for your help,
