I have task to build new Microsoft exchange 2010 or 2013 environment for 60 users. The users will be send & receive emails internally and externally. Can we build server with all server role (CAS, Hub ,mailbox etc. ) in one server and customer like go with all role in once server, since they are beginning the business and they do not want to spend too much money on servers to have individual server. If so,
How much cost will be MS exchange licencing?
What server configuration would be best if installed all server roles in one server?
I suggest to go with Office 365 for cost efficiency and less administrative work, however customer still not go for cloud option and they like keep their exchange server in house datacenter .
I would like to get some advice from experts and get some idea / comments then start build some test lab by own and test all functionality before I go and implement the exchange.
Also please include, what is best solution for this customer office 365 or MS exchange 20XX?
Thank you in advance
