Hi Guys,

I am experiencing internal email flow issues in my organization.

User A sends email to user B and C and sometimes they received and sometimes not.


The messaging tracking tool shows the emails as pending or unsuccessful:

Pending
15/11/2013 15:01 hq-cas2
Delivery for this message is delayed. The system will continue trying to deliver the message.

15/11/2013 15:31 hq-cas2
Delivery for this message is delayed. The system will continue trying to deliver the message.


In the The event viewer in hq-cas2 shows eventID 8010 - Remote Delivery ( see attached ).

I got a CAS array ( HQ-CAS1 adn HQ-CAS2 ) both have the transport role installed, problem happens on both servers.


Any ideas ?

JayCarter82,

I ran the "Get-MailboxStatistics" command and to check the mailboxes size and they all are below the limit.

Also, when i look into the "queue viewer" there are a couple of emails stuck in the submission queue with the "A storage transient failure has occurred during content conversasion" error.

Are these servers running server 2012 at all? If so, it appears to be a bug acknowledged by Microsoft, according to this thread:

Hotfix rollup 2 for SP3 here:

Try installing that and give them a reboot?
