Hello, We do a full migrationfrom Exchange 2003to Exchange 2007 and W2K domain to W2K8: I re-created the address lists for departements in complement of theGlobaladdress list.... Can anyone tell me why my Outlook 2007 clients have chosen for thedefault Addresslistthe first alphabetical listinstead of keeping theGlobal list. Under Exchange 2003 I had these lists, but theglobal list was always the default and users who wanted could choose another: it is this situation that I want get. We use the cached mode:So I think it has something to do with the OAB (Offline Address Book), but how ?We are currently in the situation where the mailboxes are linked mailboxes with theusers in the source domain, the Exchange 2007 server is in the target area and the cloned users and groups (cloned by ADMT) with SID history Thank you in advance

are you able to see all the Address lists when you connect in Online mode? Also check if your clients have downloaded the new OAB.?

Hi,Is that difference when running Online Mode for Outlook 2007? Whether any error message come up in the Application event log or Outlook when upding the OAB?If possible, please capture a screenshot for the problematic OAB when using Outlook 2007.ThanksAllen
