Preventing Multiple Prefixes in Emails in Microsoft Outlook

"Hi, I am Gary for Expert Village. When we reply to an email, Outlook automatically places and Re prefix into our email, so we know that it is a reply. In order words it was sent and this person is responding. Like we see here in this email, the email automatically has the Re which means it is a reply to an originally sent email. Now emails because the correspondence can go back and forth many times, the Re, the reply prefix gets added on each time to the original Re. So in oder words theoretically, if this email was going back and forth there should be an Re prefix, the Re prefix should be added each time. So, what would happen is if that was the case, everytime you had a correspondence you have an email that looks like this and the Re would just keep getting added, added on and on. But what Outlook does is that it is suppose to identify the first three characters followed by a colon. Many time it sees alpha characters followed by colon, three or less of those alpha characters, it automatically will identify it as a prefix and will remove it and create a new one. So it will always left with whatever is there, it will always create just a single prefix and it will look similar to this email here, no matter how many times the correspondence goes back and forth. But the reason this email has a chain of Re's is because the first Re had a space in front of it and it wasn't through alpha character, it was a space Re and therefore Outlook did not pick up that it is a prefix with the three alpha characters and a colon. It didn't remove it and it didn't create a new one, so it just kept adding on a new reply to this chain of prefixes. So that is the reason why this happens if you have an email that looks like this. The reason why it is important to know this feature is because if you wanted to send an email with a specific keyword in it, so everytime you receive the email from that person, you can identify it in your inbox, you can put it within some type of non alpha character. In order words you can put a keyword inside a bracket in front of the subject line or something similar to that and you will always know that you will always see that keyword, it won't be deleted by Outlook."
