Finding original email is quite difficult due to their duplicates. From this article, you will come to know why multiple duplicates of same emails appear and how to delete duplicate emails from Outlook securely and instantly while vital emails remain intact.
MS Outlook is an easy-to-use email application that helps users manage, receive, and share multiple emails. If you've been utilizing MS Outlook for some time and have a few dozen or even a couple of hundred messages in your inbox, then you're well on the way to have never confronted the issue of duplicate messages and this will scarcely transpire soon. Fortunate you are! : )

Yet, to be honest, I've never met an individual that way. It's evaluated that a normal Outlook client gets around 50 - 100 messages per day. Along these lines, we ordinarily have a huge number of email messages stuck in different folders and you may not have an ambiguous thought of a number of copied emails really are in your Outlook. 

 What are duplicate files?


A duplicate product may be anything, like an email message, note, calendar,  contact, task,  or may be an attachment and occupies the equal amount of storage space like original email has after duplication. Such files saved in the inbox or archive folders in Outlook are called duplicate data files. Some emails also created by the ads, newsletters, press release, or offers for new items etc. Other reasons of Duplicate Outlook Emails are discussed below.


Common Reasons of Increment in Duplicate Emails in Outlook:


  • Receiving Same Emails: You may receive numerous duplicate emails either from your co-employees, friend, or client. Sometimes, advertising companies or associations revert you the similar email, newsletter or press release multiple times to gain your attention for their scheme.
 
  • Incorrect Synchronization: Another reason is an interrupted or wrong management with a laptop/mobile device. For example: if you read some emails on your Smartphone and others on your computer system, then the location of emails shifts to a different folder on every device.
 
  • Mail Server hiccups: Sometimes, duplicate Outlook emails get created by the Mail server hiccups, specifically, if you enable the "Leave Messages on the Server" settings option. Wrongly organized MS Outlook rules,  when two or more "move a copy to" rules used to particular receiving email also result in duplicate emails in Outlook.

  • PST Merge and Improper Mailbox Settings: When you try to merge various Outlook PST files into a single file may lead to email duplication. If the mailbox setting is not correct creating an Outlook account, then you may receive the similar emails and other items multiple times.
 
  • Duplicates created by Antivirus Software: Also, even your antivirus software may generate duplicate emails. Obviously, it won't do this purposely, it may be only an irregular reaction, particularly on the off chance that you tap the "Send/Receive" button very frequently meddling in the planned send/receive/save procedure.
Whatever the reason is, numerous duplicates of a similar Outlook emails may bring about bewilderment and confusion in your MS Outlook account, making your work more unpleasant and less profitable.
 

Issues that Appears by Duplicate Outlook Emails:

As you likely know, Outlook is an awesome application mostly used by the small and large organizations to enhance business productivity. The problems that  cause duplicate Outlook emails are as follows:

  • Lack of Memory Space: Duplicate emails of Outlook occupies the same amount of space like original emails. This result in maximum usage of memory space only by the same emails. Due to insufficient storage space, the upcoming emails get delayed.
 
  • Poor System Performance: If the load increases on the Outlook account, then the Outlook process speed performance starts reducing and your system may start hanging or freezing.
 
  • Email Corruption Increases: Once the emails duplication increases, then the saved emails may get damaged, formatted or corrupted due to mishandling of Outlook emails.
 
  • Slow Email Send /Receive/Open Process: If space is less, due to duplicate Outlook emails then it easily affects the open/send/receive process of emails and takes too much time to get processed.

Hello
 Manual techniques mentioned above are the best wy to remove Outlook's Duplicates.I tried all the manual techniques to remove Outlook's duplicates, But unfortunately, i could remove only a few duplicates outlook's files as there are lots of PST files and damn big attachment in my Outlook  and
So, left with no choice I used SysInfo Outlook duplicate Remover. With this tool, I managed to remove all Duplicates in a single run.

This is so misleading.

I want to delete actual duplicates, not redundant emails from conversations. By an actual duplicate I mean an exact duplicate - as if you copied and pasted an email into the same folder.

Outlook Clean up function seems to only work on redundant emails - those are emails from a conversation where the Reply includes the information from the previous email.
The Modifying View settings method also only works on emails that aren't exact duplicates. Exact duplicates have the same modified date and time.

I work in an office where we are not allowed to have third-party add ons and am dependent on MS for solutions.

Is there any way without add ons to remove exact duplicates from Outlook 2013?
