Top Methods to Delete, Remove & Eliminate Duplicate PST Files in Outlook


It might be difficult to keep track of everything in your Outlook inbox, especially when it’s filled with identical emails. Not only do these duplicate messages take up precious storage space, but they also make it harder than required to sort through your emails. Thankfully, there are successful remedies for this common problem. Eliminating duplicate emails is essential for keeping an ordered inbox, no matter whether they were brought about by importing emails from another account or over time.


Reasons Why Outlook Has Two Email Addresses

There are several reasons why you could have duplicate emails in Outlook, which can cause mess and inefficiency in your email handling. Finding the causes of these duplicates is the first step in fixing the problem and guaranteeing a more orderly, clean inbox. These are a few typical reasons why Outlook produces duplicate emails:

  • Email account configuration: If you’ve configured your account in Outlook more than once, it can keep retrieving the same emails, which might result in duplicates. When people try to fix connection issues by adding their email account again without first deleting the old one, this is a typical result.
  • Email import: Duplicate emails can arise when importing emails from Outlook data files (.pst) or other email clients without first filtering out pre-existing messages. This frequently occurs while recovering Outlook data or switching to a new machine.
  • Incorrect email rule setup: Incorrect email rule setting is one of the main causes of duplicate emails in Outlook. Duplicate emails can accumulate if the rules for sorting or moving emails are configured improperly, causing the identical email to be accidentally sent to your inbox more than once.

How Do I Get Outlook to Stop Sending me Duplicate Emails?

In order to stop duplicate emails from appearing in your Outlook inbox on a regular basis, you must take care of the underlying issues. The following are some practical methods to get Outlook to stop sending duplicate emails:

  • Examine and modify the email guidelines: Misconfigured email rules are a typical source of duplicate emails. Examine your Outlook rules to make sure duplicate emails aren’t being sent, and make sure there aren’t any incompatible rules that might lead to an email being copied or moved to many folders.
  • For synchronization, stabilize the internet connection: Maintaining a steady internet connection is essential to ensuring that Outlook synchronizes with the email server correctly. Multiple email downloads can result from a weak connection. In particular, make sure your internet connection remains steady when Outlook is fetching emails.
  • Set up the Send and Receive options: Duplicate emails can arise from send/receive intervals in Outlook that are too frequent.

To Get the Ideal Frequency, Change These Values as Follows:

  • Access Outlook and choose the ‘Send/Receive’ tab.
  • Choosing ‘Send/Receive Groups’ and ‘Define Send/Receive Groups’.
  • Opting for a more realistic duration, such as 15 to 30 minutes, while setting the ‘Schedule an automated send/receive every’ option.
  • Click ‘Close’ to verify your changes.
  • Appropriate mailbox configuration: Email duplication can result from incorrect mailbox settings, particularly when configuring your email account in Outlook. Make sure your account settings are adjusted correctly by reviewing them.
  • Limit the number of account setups you make: Setting up the same email account on different devices or in different versions of Outlook might cause duplicate emails to be sent. Try limiting this by using the same version of Outlook on many devices or establishing your email account on fewer devices.
  • Revise Outlook: Using an out-of-date version of Outlook might cause problems, such as multiple emails. Update your Outlook program frequently to the most recent version; updates frequently include patches for common glitches and issues.
