Office 365 Subscription

[camdave]

My wife and I have a desktop each (also a tablet and two mobiles) which we run totally separately from each other. We have our own IDNet and Gmail accounts and I also have a Yahoo email address. When we are at home all emails are dealt with via a desktop client. There is no requirement to synchronise our emails.

My question is; if I move from Office 2007 to Office 365 on subscription, partly so that I can get Outlook 'cheaply' and upgrade at the same time, is it possible to not sync. the PST files. I know you can sync. across multiple devices but that is exactly what I do not want to do.

I would point out that we do have access to each others desktops - it is a matter of convenience not privacy!

Can anyone help me with this?  All references I can find on the internet  tell you how to synchronise only.
