Exchange email accounts use Active Directory user account credentials. If the Exchange user account password you entered in the iPhone was either entered incorrectly or subsequently changed by someone, then when the email application trys to authenticate to the Exchange server through AD, the account will get locked after the account lockout policy requirements are met.

I've actually had the same problem here. I work at a university, and oddly enough this problem has only happened on one phone out of about 20-30 that we've set up.
The username and password is correct on the iPhone, because after it's unlocked it will then connect and download emails and calendar entries as normal.
It seems to lock the account at random, but occasionally it will lock the account again and again back to back.
Anyone with any advice, I'm happy to hear. I'm on hold with Apple's iPhone support now.
I'm having the same problem. I have change mail to POP back to exchange, from push (15min to 1 hr) to Fetch, Fetch to manual, and SSL on to off. The funny thing is that this wan't not a problem until I change my network password. It connected fine previously without any locking of the email account.
I'm not changing my password at all during all of this and after the SA unlocks my account (done about 30 times over 2 weeks now) it connects and pulls down mail right away.
Is there a setting on the exchannge server that can help debug this?
What I have noticed recently is that when I have stop syncing my calendar and contact the locking has stopped happening. I noticed that my cal appts were not getting updated and when I stopped the syncing and started syncing again I got all my meetings on my phone.
I'm not sure if someone might have fixed/changes something on the exchange server side but I think this might be the fix to the problem... so far.
