Hi guys, I have exchange 2003 and outlook 2003. Since we have changed some month ago the server the OAB stops being downloaded. The process of building oab is ok.. Folders of OAB created correctly it seems (versions 2,3,4). Outlook profiles, when there have been the migration, have been recreated via PRF files. Well, every send/receive action returns a 80004005 error in synchronization activity of offline address book. The strange thing is that yesterday I have rebuilt the oab on exchange, then I have created a new Outlook profile on my pc and it worked! Then I have created another new profile via PRF file and it does NOT work! Well... have you some good explaination to this behaviour?? Thanks in advance! Bye Francesco
