Being an Outlook user, it’s a very common situation to have duplicate items in the form of email messages, contacts, calendar entries, tasks, notes as well as attachments in Outlook data files. These duplicate items may cause some serious problems, such as Outlook email client application will start to slow down in performance, having multiple copies of the same item may cause great confusion or disorder in Outlook, the mailbox size will be increased or exceeded, and many more.
There are many reasons due to which an Outlook user can have a large number of duplicate items in its mailbox.
The above are a few common reasons which cause duplication in Outlook mailbox data. If the duplicate items are not removed or deleted from Outlook, they will increase the mailbox size or sometimes exceed the size limitation. As we know that Outlook data file aka PST (personal storage table) has a definite file size, i.e. 2 GB for ANSI PST and 20 GB for Unicode PST. If you are using Outlook 2002 or any earlier version of Outlook, the increasing number of duplicate items in your PST file will increase its size too. And if it exceeds the size limitation, i.e 2 GB, the file may become inaccessible or corrupted. We all know that an oversized Outlook PST file is prone to corruption.
To avoid corruption in PST files and to enhance the performance of Outlook, you must remove or delete all duplicate items from your PST files.
