To practice Exchange I would setup my a test network with AD and Exchange, bounce it around try deleting things, moving mailboxes, etc.
Put an Exchange server in one tree and another in a different tree. Try to simulate an enterprise environment.
For good technical stuff, visit www.techrepublic.com and www.swynk.com.
In the past I've lurked in the microsoft newsgroups, looked for problems and tried to find an answer for them.
There is a ton of microsoft newsgroups for Exchange. Have fun.
BTW, I'd also recommend the O'Reilly books.
