I have a client that has an SBS2003 Server, who's e-mail outbound volumes have grown enourmously to circa 350,000 e-mails per month. Their store size is about 58Gb and there are 30 users at present. This seems to be putting a heavy load on the SBS server, and we are often getting notifications about the queue lengths on the current server.
As Exchange has become more critical to them, we are looking to create a seperate Exchange environment, and I therefore have the following questions:-
1. Can i remove the Exchange funtion from SBS2003, and have implement a 2008R2 server and Exchange 2010 without too many difficulties?
2. Should I just be looking at Exchange Standard as oppossed to Enterprise.
3. Is it fair to assume that with a decent Internet connection Exchange 2010 will comfortably handle in excess of 300,000 outbound e-mails per month.
4. Is there anything else I should be aware of when sending this volume of e-mail (all opted in recipients, no spam).
We will be retaining the SBS server for all other existing functions. Any help would be appreciated.
