When set to display emails in conversation threads, eM Client appears to do so based on subject. It looks at all stored emails when doing so.
Generally, this is good. But sometimes you have two totally unrelated conversations that happen to share the same subject. In this case, eM Client will put both emails into the same “conversation” even though they are in different folders.
Is there any way to fix or work around this? Is there some way to tell it that a particular email is not part of a conversation?
