Issue 
A report subscription with Active Directory Window Users as Recipients will fail when delivering the report 
The subscription will fail with the following error in ION_SystemLog: 
ION Web General    ERROR    2020-05-21 19:31:31.877    Subscription Renderer    Service    SendSubscriptionNotification    Server Name    Exception sending notification for subscription '6'.

Report Subscription 
Cause 
There are two causes for this issue: 
2) Missing config file XML that controls how to log this into SystemLog
Resolution 
1) Update SubscriptionRenderer.exe.config
- Add the following section after the <configuration> tag (in the begging of the file)
<configSections>
<section name="loggingConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Logging.Configuration.LoggingSettings, Microsoft.Practices.EnterpriseLibrary.Logging, Version=5.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" requirePermission="true" />
</configSections>
<loggingConfiguration configSource="diagnostic-log.config" />
It should like similar to this:
3) Restart IIS and ION Application Core service (that will force all the ION Application services to restart)
This will allow the report to be delivered by email for the windows users (active directory). 
Additional Information 
This may be addressed by the future release of a software cumulative update (CU2).
