We are tracking a replication failure issue on our email reports systems in ExchangeDefender. This problem was caused by some schema modifications that went in place on Monday.
We have identified an issue with replication of data to the servers that generate email SPAM reports. While the reports do run correctly, they do not report any SPAM because no data has been replicated to them. This is obviously incorrect and has required us to completely replicate all data from master servers, leading to nearly a day of missed reports.
All systems should be back to normal in a few hours.
In the meantime, please remember that email reports are merely a convenience, the recommended way to access quarantined SPAM is through the control panel at https://admin.exchangedefender.com and any reports sent from there (domain admin panel) will contain correct SPAM counts because it is ran against the master databases.
