I transition from a Exchange 2003 to 2007, the only thing I kind of messes up is that I forgot to upgrade the mail policy prior to decommisioning the old exchange 2003 but it was working anyways. I was able to modify and create new accounts. Recently in the past few days I have not been able to modify or create any new mailboxes because it indicates that the "server address list service failed to repond". This is a production server and we currently cant create new users mailbox because of this error, been researching all over the net but had yet to find a good site that helps me fix this. Any direction or assistance will be greatly appreciated before I have to pay for MS support ticket.\ Thanks Amador

Same problem here, transition from an Exchange2K3 to 2K7 and no way ton update or create new mailbox. Did you find the solution ? Boris

Has anyone found a solution to this? I am getting exactly the same error when trying to create a new mailbox or public folder store:The Exchange server address list service failed to respond. This could be because of an address list or email address policy configuration error.I have 3 exchange 2007 servers and 2 exchange 2003 servers, The mailbox role is on windows 2008
