I have created a Public Distribution list and have verified that it was created and in the correct mail store. When I search for it in any of the directory handles (to chose it as a limiting parameter) I do not see it listed with the other Public Distribution Lists so I cannot select it.
I am running Unity 4.0(4)SR1 using an off box corporate exchange server. I am running a failover unity server also. I forced an AD sync and waited over 24hrs but the PDL is still not available as a choice. There are several members in the PDL that I verified by looking at the PDL's AD account.
