In the U.S., daylight savings time started on November 2 at 2:00am. Which means that at 2:00am, it was suddenly 1:00am. At that moment, Essentials lost its ability to send email.
I maintain multiple Server 2012 R2 Essentials machines. Each one emails its health report at 6am. On all three, on the Health Report tab, at 11/2 1:00am, I see the message:
Status: Cannot send email.
Error: The Windows Server
Essentials Management service is not running.
That message repeats on November 2 and 3 at 6am, i.e. at the times when the reports should have been sent.
When I right-click on a report and choose Email the Health Report, it shows “Emailing report…” but never finishes. If I stop and restart the dashboard, it is back to “Cannot send email.”
Reviewing my email history, I see that I did receive the 1:00am emails, even though the dashboard says “Cannot send email.” However I did not receive the subsequent 6am emails.
Workaround: Restart the Service
The Windows Server Essentials Management service is running and I doubt that it stopped. I decided to try restarting the Windows Server Essentials Management service. After that, when I sent a Health Report email from the dashboard, it went out immediately.
It seems there are a couple bugs here:
- The Essentials sever tries to send an unscheduled health report at the beginning of Daylight Savings Time.
- The Essentials sever cannot send email after the change to Daylight Savings Time.
Fortunately the workaround is simple: restart the Windows Server Essentials Management service.
Update November 8, 2016
As several have reported in the comments below, this issue continues two years later. In the US, on November 6, 2:00am became 1:00am. Essentials tried and failed to email a Health Report at 1:00am, and has failed at 6:00am every day since then. The reason given is still, “The Windows Server Essentials Management service is not running,” even though it is. After restarting the Windows Server Essentials Management service just now, I was able to manually email this morning’s report.
