Mail flow between exchange servers 2007 inside organization We have set up 2 exchange servers 2007 in domain: test.gg-ds.com Firs is for example: mail1.test.gg-ds.com Second is for example: mail2.test.gg-ds.com We have smart host for routing like: coolmail.gg-ds.com, but I dont think this matters. Everything work fine except messages from server2 to server1 PROBLEM: When sending messages from mail2.test.gg-ds.com to mail1.test.gg-ds.com the messages are stuck in a message queue. ERROR MESSAGE in queue viewer: Last Error: 430 4.2.0 STOREDRV; mailbox logon failure Did all possible that came to my mind: disconnecting database, restarting exchange transport service, checking settings. Have no ideasL Help Greetings Alex

Hi So now I solved the problem, but I am in doubt that other things could get stucked. I have changed a Microsoft Exchange Transport to log on as local account and that solved all transport- queue problems ;) Are there any problems with these settings? Greetings and thanks for all your help Alex
