Unexpected data in the MessageStats report related to Mimecast
说明
The Last Message Received in a Group List report isn't showing all records from the past and some date columns are displaying unexpected date values (i.e."0-Jan-1900") which are discrepancies compared to what is shown in Mimecast.
原因
There is a limitation imposed by Microsoft where we can only retrieve messagetrace data up to 10 days and 90 days of overall Historical data.
解决办法
The unexpected dates in the report for some of the data are occurring because Nova does not process traces with the status "failed" as Mimecast does. Other than that, unfortunately, this is an expected product behavior due to technology limitations as explained in the cause.
