I have just upgraded to Office 365.  Outlook was working perfectly on my PC and 2 ipads.  Then I added another PC to the system and it has gone haywire.  Firstly, the email accounts on the 2nd PC are unreliable, in that sometimes they get the mails addressed to them and others I get a message "cannot synch subscribed folders" etc.  ( I have a gmail account, an old orange (FS) account and 2 private ones)  At the same time all computers are now having copies of all the emails over the last 3 or so years downloaded to them, in batches of 30 or 40.

All I want to do is to have the same emails sent and received on each of the computers. 

I would also like to copy all my saved emails, in their the specific folders from the old PC to the new one.  Can Office 365 do that?
