There is an issue w/the PIN lock requirement for Exchange accounts on the D2 (and DX as of 2.2 update)...if you have an Exchange email account added, even if the PIN lock requirement is not enforced by your company/server settings, the D2 will still require setting up and using a PIN to unlock the phone.
Someone posted a potential fix (works on their DX) on Droid Forums:
I can't test this, as my company does enforce the PIN requirement...thought others might want to give this a try.

I did find a fix for the pincode issue for Froyo on the X. The minute I updated to froyo, this pincode issue showed up on the X.
If you login into your webmail (OWA access), and go to options, and the delete your phone's from your profile. Then remove the account from your phone, reboot the phone, and readd the exchange account, this removes the pincode on Froyo on the X. I found this fix on the froyo bugs thread on this forum.
Worked perfectly for me
