Can you provide a little more information? For example, are all of the messages stuck in the queue going to the same external domain? Are you doing DNS lookups for routing Internet email? Or are you forwarding to a smart host? If you look at the messages stuck in the queue, what error(s) are being reported? Any further detail you can provide will help in troubleshooting this issue.Lee Owens, MCSE, MCITP: Enterprise Messaging Administrator

Hi,Did you look in the application log for clues?Did you try the mail flow troubleshooter (in the tools menu)?Leif

I would also check your Firewall/Router and/or SMTP Gateway devicefor any issues. Are youusing a Smarthost? Any issues with the Smarthost or ISP?MVP Exchange Server
