We have our exchange 2007 server currently on Virtual Iron, and are migrating it to Xenserver. I attempted to do this over the weekend with platespin and it seemed to work fine except I could no longer send email. All serices started, I could recieve email and log in with outlook and owa. However when I sent email from either outlook or owa it sat in the outbox and wouldn't send internal or external. however, programs like IPmonitor were able to send using the SMTP protocal. Does anyone know why this would be? Does anyone have any suggestions on how to try this again next week and have it be sucessful using platespin? I did not stop any services or anything this attempt, and used a block based vss transfer. Thank you for any help you can provide.
