Change category rule when email is responded to

[scottb]

Hi everyone,
We have a shared email box that applies a category to received email that flags their category as blue. Can you apply a similar rule to change the email message in the inbox to green once it has been responded to? Not sure how to create that rule.
Thank you for any help.

I could be mistaken, but a rule fires off when an email is received or when a message is sent. I'm not sure if there is a rule event to trigger the rule when an email is responded to? You might have to investigate if add-ins can do this, else search for some VBA code that can change the category when one replies to the mail.

Rudi,
Thanks for your reply. I will keep digging.
Thanks!

I think this will be really challenging. When someone clicks the reply or reply/all button they get an opportunity to create an email, but it will be hard to determine that that specific email was actually sent.

Edited to add, I suspect that this post may have enough information to enable you to develop an add-on that could do this for you.
