Sorry AphJN I do not quite follow you this time. There was an outlook version on the laptop (it was my only PC at the time until I bought a Desktop), but the information on this Outlook was not up-to-date since I then started using the Desktop. I know I can copy onto a memory stick and take it to the laptop, but this seems to be defeating the object of a home network.

Given I cannot sync how can I share the 1 pst over the home network? I also do not understand your reference to "It's also possible on the laptop to attach or open the Desktop PST as a personal Archive and not the main Outlook pst. (it will still be name Outlook.pst, but in the laptop it will show as a personal archive.)" How is this done?

Thanks again

Gareth
