I have SBS2011 / Exch 2010. Users have Outlook 2010.
Suddenly users are NOT getting emails(both internal & external). So I send an email to myself in my outlook and it does not get delivered. No bounce-back email either. I checked "Develiry Confirmation" on my test email, but get no confirmation.
In Services.msc, all exchange related services are up and running. I even rebooted SBS2011 and disabled Symantec EndPoint Proection Anti-virus software on SBS as well, but to no avail.
Users can bring up Outlook 2010 and run OWA (https://remote.domain_name.com/owa/
Can you help?
Where should I look to troubleshoot this issue?
