I am doing some research into a suitable design to move a client from a SBS 2003 single server to perhaps multiple servers due to the heavy exchange usage and/or TS requirements.
Presently there are approx 16 Users where about half work remotely on Laptops and VPN in to collect email and access files. They are presently heavy users of email with Exchange 2003, where there are multiple 5GB+ mailboxes - restrictions on mailbox size were lifted some time ago which has given Users free reign on email. In saying that, I am interested to hear what people of done for mail archiving solutions.
The plan at this stage is to beef up with a new SBS 2008 Server with 16GB RAM, but wanted to consider other designs.
