Exchange 2010 Server Not Sending or Receiving

Needed to reboot our domain server, so we also rebooted the Exchange 2010 Server after that.  However, now it is not routing the emails internally or externally.  No one is receiving them, although the Outlook app on our local PCs say "Connected to MS Exchange" and email does get sent out of the Out Box.  We've tried rebooting it again, tried restarting or starting all the services with no luck.  Any ideas?

After using the MS Exchange Management Console's Mail Flow Troubleshooting Assistant, we obtained the following information.  It said that "Server xxxxx has the Hub Transport server role and the following services are not started:  MSExchangeTransport.  These services need to be running for mail to flow properly."  We opened task manager on the Exchange Server and started the MSExchangeTransport service; however, after a minute or two the service goes back to "Stopped."  Any suggestions?
This sbs?

Check the time synchronisation between the exchange server and the domain. Once that's done (assuming that's the issue), restart the Microsoft Exchange Active Directory Topology service. I had a similar problem recently. The time issue was indicated in the event log as the reason the service kept stopping, so it's quite possible you have a different problem.

If it's not the same problem, please post any relevant Event Log messages and I'll see if there's anything that I can help with.

Turned out that we found the following article that solved our problem.  It seems that bundled with TrendMicro is an app called ScanMail and sometimes when it runs it doesn't allow the MSExchangeTransport service to run.  It seems what happened was that the two ScanMail services were not running when Trend Micro was first installed (about 3 weeks ago), but when I rebooted the Exchange Server this morning, the two services must have started running.  After we uninstalled them using the Exchange shell as per the article below, email began flowing.

Even though the article we found seemed to have worked to enable email to flow, giving you credit because when I looked at the Exchange and Domain servers, they were 4-5 minutes apart, which could have caused us problems in the future.
