When you have emails being saved automatically by MacroView Corporate Email Filing (CEF) you may need to create an email filing rules blacklist to prevent specific emails from saving even though they may match another of your filing rules.
This is achieved by creating an additional rule which should be at the top of you filing rule list so that it is checked before any other rules are processed and which points to a location that does not exists.
Sample Corporate Email Filing blacklist rule
The below example will not save any received email containing [PERSONAL] or [CONFIDENTIAL] in their subject even if they match another filing rule later in the rules configuration file.
<Name>Do not save emails with subjects containing [PERSONAL] or [CONFIDENTIAL]</Name>
When an email matches the above rule, because the https://tenant.sharepoint.com/locationdoesnotexist location cannot be found the email will not be saved and MacroView Corporate Email Filing will not check any further rules.
Tip: If you want to prevent an entire rule for firing temporarily without removing it from your rules configuration files, you can simply set the <RuleEnabled>false</RuleEnabled> setting to false.
