We are getting the following error after CU6 implementation:

Seems like a latency issue... But, all tests are succesful, we are not experience any harm/issue. So, can we consider it as "by design" or should we take action?

Mailbox Transport Submission - the verification that the probe messages were successfully submitted within 5 minutes to HUB has failed.

This could indicate that the mailbox submissions are taking too long or not progressing at all.

SequenceNumber: 635484312145508431

Error: MapiSubmitLAMProbe finished with CheckPreviousMail failure.

FailureContext: MapiSubmitLAMProbe finished with CheckPreviousMail failure.

ExecutionContext: MapiSubmitLAMProbe started. This performs - 1. Submits a new message to Store 2. Checks results from previous Send Mail operation. Sequence # = 635484312145508431. First Run? = False. Previous mail submission to store was successful. Results - # of previous results: 0. Could Not Find stages that ran. Previous SendMail failure - Mail submitted to Store during the previous run never reached SendAsCheck.

This may indicate a latency from Store to Submission Service. Investigating. Found lower SA latency. Indicates an issue in Submission service.

Hi,

Based on my search, this event can be ignored and is a cosmetic issue in Exchange 2013, if we are not seeing any transport issues in the productive environment.

Best regards,

Belinda,

any publicly accessible reference about that ?

Have that in my CU8 Lab as well and feel they might have fixed it meanwhile...
