Recently added an Additional DC in the domain and installed exchange 2003 on it. Then move all mailboxes and remove exchang from the old server. Then demoted the old server AD and its now a member server. In outlook the clients get connected to the new exchange server name without problems. If they have mail or items in outbox, when outlooks opens, they receive mail. The main problem is when they click send receive button in outlook they get an unknown error )X800401119 I deleted and created an new global address list in system manger and deleted and recreated a new offline list too and added the global address list to the offline list. When creating a new message, when they click to they can see all the users and send mail with no problems. When i tried downloading the address offline book it gives the same unknown error. When i try to rebuild the Offline address list, i get OALGen encountered error [0x8004010f] while calculating the OALs. What the bloody hell is happening. The users can login with new AD on the ADC and even login their exchange accounts but still this send/receive business is really irritating. Need urgent help! I need help
