If your Outlook data files are corrupted or damaged, synchronization can misbehave. That may cause previously downloaded emails to get re-fetched or duplicated. Running built-in repair tools like <strong>scanpst.exe<\/strong> or recreating the data file can help fix this.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1765351185700\"><strong class=\"schema-faq-question\">Q: Why does my Outlook inbox show duplicate emails only when I check from multiple devices?<\/strong> <p class=\"schema-faq-answer\"><strong>Ans:<\/strong> When you access the same email account from more than one device, especially using POP3, each client may download the same message independently if the server keeps a copy.
