Re: Connecting 2 offices….
OK, if Exchange is absolutely, definitely not needed (now or in the future) you may be cheaper going for 2 x Standard Edition. Check your local pricing first.
Most routers support VPNs — Cisco is the “creme de la creme” but Vigor, for example, do an excellent job for much less £££ (or $$$)
btw, we’re all assuming you have some high speed internet connection at both sites — would you care to confirm that?
And yes, with the VPN, either office will be able to log onto the other ones server, just much slower than locally, hence my suggestion of two servers
