How much RAM for small Exchange 2010 installation
I'm doing my first Exchange 2010 installation on a new Dell T610 server. The server will be an additional server in a 2003 domain, but will be running Server 2008 64-bit (obviously). There are only 20 Exchange users, but that one server will be handling all the Exchange functionality. How much RAM do I need as a minimum? Thanks.
Whereas only 20 users, unless they have a lot of mail, I would say that 4GB of RAM are sufficient.

Yes, I read that before asking. I suppose it's doing "multiple roles" according to this article, but do I really need 10Gb? Sounds totally OTT for 20 users... Thanks.
Exchange 2010 is exclusively 64bit and RAM is not really that expensive now. I would say for an organization of Upto 100 users with heavy usage 4-8 GB should be great.
Sometimes it is not just the number of Users who will be using email, but sometimes it could be mail spikes, Mailstorms or maybe a Spam attach which can consume resources rather quickly. So I suggest 4-8 GB :)

Hi 4GB is recommended.

Thanks for the comments. I suppose perhaps what I should have asked is: "Will Exchange actually install with these multiple roles onto server with 4Gb RAM, or do I really need 10Gb per the article to permit the installation itself to run?". I don't want to have to turn round to the customer and say "I'm sorry, but I just can't install it". They've being very mean on costs. If it were mine, I'd proably throw 16Gb at it to be sure, but it's not... Thanks.

Thanks for all the help and comments which I have taken on board.
Exchange eats RAM, so don't be surprised to see most of your RAM being used up by store.exe.
I have 24Gb in my 2010 server and 17Gb is regularly in use by store.exe.
