I have exchange 2007 SP3 running on server 2003. I just performed Windows Update and it installed Update Rollup 5. Right now I can’t get any email back from Outlook or OWA. I don’t get an NDR, just…nothing. I can address an email, send the email but don’t get anything back.
Ran the tracking tool (mail flow) and it has problems connecting to SMTP port 25, 587. But I can telnet to these ports just fine. Also fails Mail Acceptance test- error submitting email. Ran through other tests and In tracking logs I see messages like STOREDRIVER, DELIVER…. What else should I see?
I honestly do not know where to start. Please give me some steps I can take to try and resolve this!
