When using Systems Center Operations Manager , if you configure Notification Recipients or Subscribers with the option of "Only send notification during the specified times" and you configure it with only an exclude range (like "Except from" with a time range of, say 1:00am to 7:00am for example), email notifications fail altogether.
In the Operations Manager event log you will also see the event below:
Log Name: Operations Manager
Source: Health Service Modules
Date: <date> <time>
Event ID: 31501
Task Category: Notification
Level: Warning
Keywords: Classic
User: N/A
Computer: <RMS Server Name>
Description:
No primary recipients were specified for the notification or all recipients are unavailable according to the schedules. Notification will not be sent
One or more workflows were affected by this.
Instance name: Alert Notification Subscription Server
Management group: <Mgmt Group Name>
So to keep this from happening, or to fix it if you’ve already found yourself in this situation, you need to configure the Recipient or Subscriber first with an included time range, then configure your excluded time range.
For example, first configure you include Range like Date | Range = Always | Time Range = All Day | Weekdays = Week days. then once you have that, configure your Exclude Range like Data Range = Always | Time Range = Excluding 1:00am to 7:00am | Weekdays = Week Days. The screen shot below shows this configuration.
