Hi team,

We have the subjected error message generated from an application trying to send mails, i understand this is an issue due to usedversionBuckets from Backpressure rejecting the messages of application.

 

However, my concern is we have a pool of exchange servers sitting behind the load balancer smtp-relay, and i am not sure how to check on which exchange server rejected the mail from this application, through technet i got to know that we will have to look for Event ids 15004 & 15005. but, we have around 60 exchange servers and not sure how to check which exchange server amongst these rejected the mails

    I'd use Powershell and search all the servers in bulk for the event ID

    Hi All,

    Thanks for your advises, we have now come upto a situation of advising the application owners to implement a retry logic in their apps as this is an unfortunate event that happens on Exchange servers sometimes when there is surplus mail-flow.
