Chi - I dont think any of these will work because in the end, Tammy needs the rule to update either a request, OR an incident regardless of what is in the subject line. For example, if the ticket was originally opened as a request, then converted to an incident, and an end user replies back to an email from when it was a request, they want it to update the incident. But in the rule, you can only specify whether that particular rule updates requests, or whether it updates incidents. There is no way for it to know whether its a request or whether its an incident without the subject line telling it that information. So I dont think this will work at all no matter what we try to set up as the keywords in the subject line.
Here is a screenshot of what I mean...the rule itself can only pick one object, either request, or incident, but not both:
So for the example, if a ticket was originally a request, and it got converted to an incident (by way of the customization that Tammy has in place), that ticket is now an Incident and no longer a request. However, if the end user replies to an email that was from when the ticket was a request (before it was converted) and the subject has "request" in it, then the mailbox rule for that subject wouldnt work to update the ticket because it's action object is Request and not incident.
Is my thinking correct here?
