Microsoft Exchange

I have just converted a Hyper V  Microsoft Exchange virtual machine to an ESXi virtual machine. The machine comes up , however when mails are sent by users they get stuck in the submission queue. All the relevant services have been started. Any Ideas

Just a guess based on an odd recent 2003 problem. Rebuild the smtp send connector.

did you restart the server after  its was converted from hyperv to esx
This happen to me just week ago. We have Exchange 2007 running on Hyper-V and attached with HP Left Hand Storage. The email queue was stuck until 7++++ mails. After checking on Exchange CAS/HTS and Mailbox server, there was no problem on these servers, nothing had been changed. The mail queue DB still have a lof free space. What we solve this problem is restart the HP Left Storage. Once restarting the storage, everthing work as normal.
