I'm using Outlook 2010, and trying to use the Categories feature of it. So, I have hundreds of emails in my Inbox, and I've assigned categories for them, and that's fine.My question is: When I send/receive emails which are in the same conversation as mails which I already categorized, how can I make sure Outlook automatically assign the same category to the new mail?For example, I categorized an email (with the subject "Hi dude") as "Friends". Now, I reply back to that mail, and receive an answer from my friend later. I want Outlook to automatically assign my sent mail and the reply the "Friends" category.Is there a VBA for that? Any other option?
