Microsoft BITS Errors While Attempting To Download Outlook Offline Address Book (OAB)

You don't need to configure anything else under the access profile properties. All of that is taken care of by the Exchange APM profile.

The messages you posted from the APM logs are not errors, they just indicate that NTLMv2 is found and that the profile is using the appropriate SSO for that request. I see those messages for successful OAB downloads (the only difference in my lab is that I'm using NTLMv1).

Do you have APM debugging turned up for both access and sso? If you can post more of your APM logs here while the problem is happening, I'll have a look.
