I´m thinking about a fitting Exchange 2010 configuration for a small business costumer and I´m not sure of some points. Here´s the situation:
The network has about 40 clients (and 40 users), one 2003 server with Active Directory and a Fortigate 60B Firewall/ Router. We have a Windows 2003-based AD and a new installed 64-bit server, which should do AD and fileservices in the future. There´s no Exchange at the moment, but the goal is to get one running. The new 64-Bit server will get the Mailbox-, Hub- and Client Access Role.
The customer would buy another server if that makes sense (definitely he would not buy 2 other servers...) and with this in mind I try to find the perfect solution for him.
Should I use another server as Exchange Edge Transport or better invest in a ISA-Server? OWA and ActiveSync are to be used. On the other hand, anti-spam features will be required also...
If the customer would do so, I´ll say let´s buy a server for Exchange Edge and a further one for ISA, but I can use only one more server (remember: only 40 Mailboxes over all).
So I have no clear idea how to best build the exchange infrastructure.
Any help would be appreciated!
