I use "arrange by date (conversation)" in outlook to group all of the emails in a particular thread
The question I have is has anyone figured out how to group two different conversation threads in to one group?
For example, a client will send an email to me with the subject of "We need two spare parts A", and as long as we reply back and forth to the same email the conversation is all grouped into one group with the same subject. But if they send me another email with the subject "Here is information about the address", it will start another conversation group, and I cannot figure out how to link it back to the original conversation.
