Getting rid of duplicate emails in Outlook PST is an important step toward reducing its size. Your Microsoft Outlook PST file is not only the most important, but it also runs out of space quickly. If your PST file is full, many things can go wrong, including the loss of emails and attachments, Microsoft Outlook crashes, the inability to send and receive email messages, and, worst of all, data loss. Duplicates in your Microsoft Outlook PST file indicate that email messages are being copied and accumulated in it. This not only takes up additional disk space but also has an impact on the overall performance of your Microsoft Outlook application. Your PST file could become corrupt over time, causing you to lose all of your crucial emails and attachments.
What Causes Duplicates to Build Up in PST Files?
Let’s address the underlying cause of the issue before moving on to the remedies. There may be numerous opportunities for duplicate accumulation in PST, and it’s possible that you won’t be able to prevent them all. Nonetheless, keeping an eye out for the reasons listed below will assist you in monitoring them:
- There is no synchronization between the folders in your PST file when you configure rules incorrectly in the Outlook application’s Settings folder. Data duplication could very well arise from this.
- Email duplication occurs when multiple accounts are created in Outlook incorrectly and incoming data is not synchronized properly.
- The same emails, calendar events, and address book contacts will repeatedly duplicate if your Settings folder is set incorrectly.
- Emails may become duplicated as a result of an anti-virus program interfering with Outlook’s sending and receiving functions.
- The PST file grows in size and becomes duplicated when multiple files are merged incorrectly.
- If the Messages Leaving option is enabled, all email messages may be duplicated.
- Email duplication can occur when you sync your Outlook account on your phone and other devices.
- Businesses frequently send the same promotional email message several times. This is inconvenient on two levels: it requires you to check the same message every time you receive an alert for it, and it consumes system memory.
Cleaning up your entire Outlook mailbox every day is a good way to avoid email duplication within PST. That doesn’t mean you should delete everything; simply delete any unwanted emails from your inbox on a daily basis. Additional methods for removing duplicates from Outlook are discussed in the following section.
