Exchange 2010 full mailbox download at new branch office
I've just set up a new branch office with it's own, connected to HQ via VPN, everything's working sweet as a nut.
When a user logs in for the first time and opens Outlook (2010) at the new branch it automatically sets up the exchange connection and then proceeds to download their entire mailbox.
As I've been a bit over generous with mailbox sizes most people moving here are going to be transferring over 1.5Gb - which on our 4 up/down connection is going to be slow and clog up everything for some time. Is there a way around this?
I know I could set up the mailboxes manually and set to only synch the last X amount of mails from say the last few months but I'd prefer an approach that works much like OWA where the mail is downloaded on request.
I realise using OWA solves the problem and I'd love to do that but people seem to love Outlook and it's hourly crashes.
If there isn't a way to do this is there anyway I can limit the amount of bandwidth used when downloading mail from 3 years ago that no one needs but refuses to delete or archive (I enforced an archive policy once upon a time and almost got stoned to death for it, the joys of working for small outfits).
