Common Reasons for Duplicates Items
Though duplicate items in an Outlook data file occur due to many reasons, below are the most common ones with their fixes:
Reason #1: Generally, rules are created in Outlook to manage email messages. For example:
- Rule 1: Move emails from contact A to folder B.
- Rule 2: Move emails containing xyz in the subject line to folder C.
Let’s suppose you receive an email from contact A that contains xyz in the subject line. Consequently, due to the rules, you get the same email in both B and C folders. You need to resolve this issue by changing the rules appropriately.
Reason #2: Suppose something goes wrong after you synchronize your Outlook profile with any other application or device. And due to this, the last batch of emails is present twice on your computer. In order to fix this issue, you need to delete the duplicates manually from the mailbox.
Reason #3: Maybe an email is corrupt on the server, and thus a duplicate is generated when Outlook starts the Send/Receive operation. You need to fix this issue by logging into the email server and deleting the corrupt email that’s creating the duplicates.
Reason #4: Outlook generates duplicates on each Send/Receive operation if the “Leave a copy of the messages on the server” box is checked on your account settings. In order to fix this issue, you can simply uncheck this option under Account Settings > More Settings > Advanced.
Reason #5: If you subscribe to a mailing list multiple times, you’re likely to have duplicate emails in Outlook mailbox. You can simply unsubscribe this service or contact the person that sends you the same emails again and again.
