  • Hello,

    First of all, I would like to tell you Why is Outlook creating duplicate emails? Please find the reasons below:

    Many things can cause Outlook items to duplicate, but the most common reasons are discussed below:

    1. An email on the server is corrupt, and thus generates duplicates when MS Outlook starts its Send/Receive process.
    2. If the ‘Leave Messages on the Server’ option is enabled, then it may result in duplicate copies of emails being created.
    3. Synchronizing Microsoft Outlook with other applications/devices (Phones, PDAs, etc.)
    4. If you have more than one alias defined for the same email account in your Microsoft Outlook profile, you will receive the same email on each alias (you will see as many duplicates as you have aliases)
    5. If you are having network or server problems, or your computer is really slow, then at one time or another you will surely come across duplicate emails.

  • Outlook can create duplicates for many reasons: sync issues, POP3 download issues, server issues, copy-paste operations, double-importing items, etc...

    The good news is that free Remove Duplicate Messages and Remove Duplicate Contacts tools available that can eliminate your dupes.
