A 400-user Exchange server should probably be fine for virtualization, but be aware that virtualization does not do anything for you regarding disk performance, the typical Exchange performance bottleneck. SAN doesn't either by itself; the disks on the SAN still must support the required number of I/Os. However, we're talking about 400 users, not 40,000.
Be aware of the support issues.

Adding more disk capacity isn't an option as there are no more drive bays, plus the box is due to be replaced in around six months so it's not viable to be throwing money at it now. We do have a 2 server ESX cluster sat on a Clariion AX4 FC SAN. Our userbase is diverse, people like to horde and never delete/archive, and I haven't helped us by not having any hard mailbox or message size limits. My rough plan for when the box was due for renewal was to virtualize anyway, and also to add a third box to the cluster. As I see it, one plan to deal with the imminent problem would be to buy some 15k spindles for the SAN and possibly a little more RAM for the ESX hosts and move Exchange onto it, job done, end of story. I'd also like to implement maximum message size limits both internally and externally, whatever you choose someone won't be happy, and my initial thoughts are that 25mb seems a figure where anything larger and you should probably be looking at an alternative means of sending. We have around 400 users and 190gb of mail (140/50 private/public store split) in a single Storage Group.
