We are currently migrating from XenServer to VMWare and we tried to do a V2V of our Exchange 2010 Standard server and everything appeared to work fine after until we realized that no one could send mail (it all just kept piling up in their outbox). They could receive mail fine which was wierd and there were no error messages in the event logs either. I rolled back the server to the XenServer one and everything is working fine. I have read online that other people have had the same issues when they tried to migrate Exchange. Having purchased only Exchange 2010 Standard am I am to bring up another server in VMWare and migrate the mailboxes over live and then decomission the old server? Not sure what my options are or should there be something else that I look at to migrate the server?
