Hey, I am having issues in sending local mails. Whenever I send an email to my Exchange User, it seems to take a 5-10 minutes before it shows up in my inbox. Sometimes it can take up to 1 hours before it ever arrives. It was working fine for the past 7 years, having this issue for the last 1 week. All emails are quened "Message Pending Submission" and sometime i have to forcefully send emails. how can i troubleshoot this issue

Hi Please post the version of exchange. You can try these ways to troubleshoot error. 1. Update exchange version to last version and install last patch. 2. Run EXBPA-> healthy check and connectivity test. Can you see any error? 3. Please restart Microsoft Exchange System Attendant, will the same issue reoccur. 4. If you install AV software, you can turn off it and reboot your server.
