I have been told you can undelete your E mails and then totally clear them from your machine to make it run faster. Does anyone know how this is done please. Thanks in advance.
Deleting emails is not going to make you computer run faster.
If you use outlook then clearing your deleted items folder may make outlook load a fraction of a second faster as it will reduce the size of the PST file that outlook uses and the smaller the file the quicker outlook will load but in reality any difference would be so minimal it would not be noticeable.
