Troubleshooting Email Delivery with ExchangeDefender Logs
Modern email delivery has become complex in order to eliminate scams and minimize the impact of cyber threats. Unfortunately, those complexities can impact mail delivery: “I sent them an email and they never got it!!!”
First point the user to https://bypass.exchangedefender.com service that’s included with ExchangeDefender. Our users love it because they don’t have to wait on the tech issue to get sorted, they can send the mail right away (and it tends to have a far better delivery success rate because we strip everything that typically trips up SPAM and security filters).
Second, find the problem in the mail and error logs.
You can of course use our interactive mail log (tracing) search to locate the message and see where the problem may be. For larger tenants, we recommend downloading the logs so you can go through them faster on your PC:
Log access gives you raw access to everything we have on our backend but you get it faster (as our support doesn’t have access to your data including logs, and getting the access approved internally takes time).
If log analytics isn’t your thing please contact us about the ExchangeDefender Managed Service where you’ll have your own postmaster managing all these issues for you (service must be enrolled before requesting support).
Email delivery problems can be complex and at times out of your control. This is why we always first recommend going to bypass.exchangedefender.com (and ExchangeDefender Inbox) so you can actually do your work. After that, grab the logs and see what the problem is. As always, we’re happy to help!
