Do imported emails from pst files get saved to Exchange Server?

Question

So I exported a user's email into a pst file and I'm importing all of them into his new email address.  My question is whether these newly imported emails will be only available locally or will they be uploaded into the Exchange server (which is TWC's
hosted service) and therefore he'll be able to  access them from his phone as well?  If they are not uploaded, how would I go about to making these emails available on his phone through his new email address as well then?

Hi th0rax,
yes, if you imported mails from a PST file to the Exchange Mailbox you will be able to Access them from Outlook, OWA and ActiveSync where you habe Access to your Mailbox.
I suggest you should do that via new-mailboximportrequest (http://technet.microsoft.com/de-de/library/ff607310(v=exchg.150).aspx) if it is a big PST file and maybe a longer
list of users.
You can also Import via Outlook but in that case you need to have that Outlook Client running until "All Folders are up to date" and the new Mailbox Content was replicated to your Servers Mailbox after the Import was done.
