1. The HubAvailabilityProbe has failed 5 or more times in 15 minutes. Last failing server: ''.
2. 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: 635703947136680580
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 # = 635703947136680580. 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
