  • If take pst file backup & restore.

    Basically, when taking a backup of PST file, there is no "restore" step. May I know why you restored your data? How did you restore the data?

    Duplicate emails could be caused by several reasons, such as:


    Multiple accounts

    Profile recreation

    Synchronization tools

    Virus scanner/firewall

    Tools to clean up the mess

    To prevent or remove the duplicate, please have a look at the following article:
