What Are Email Threads
Email threads, also known as conversation threads, group related messages together based on subject lines and reply chains. According to Wikipedia, email threading has been a standard feature in email clients since the early 2000s, helping users track ongoing conversations more effectively. Outlook automatically groups emails into threads when:- Messages share the same subject line
- Emails are replies or forwards of previous messages
- The conversation ID matches in email headers
