Why should you remove Outlook duplicates?

If you use Outlook client in your day-to-day life, you must send/receive hundreds and thousands of email messages each and every day. This will cause you a large mailbox. Being a regular Outlook user, you must be aware of the fact that PST file has a certain size limit. If you’re using any old Outlook version, i.e. Outlook 97 to 2002, the file is saved in ANSI format which has a maximum size limit of 2 GB. It can only store up to 2 GB of mailbox. Outlook 2003 and later versions save PST file in a new format, called Unicode which has maximum size limit of 20 to 50 GB. Whenever a PST file is reached to its maximum size, Outlook users face severe issues and problems related to Outlook performance. But if the mailbox size goes beyond its limit, PST file becomes prone to corruption. You should make sure that a PST files never reaches to its maximum size.

Duplicate items in Outlook cause large mailbox

The most common reason behind a large mailbox is duplicate items. Have you ever seen any duplicate item in your PST file? Do you know what exactly a duplicate item is? It can be anything, an email message or a contact. Think you’re having 1000 email messages in your Inbox folder, 100 KB each. In this way, the total size of your Inbox folder should be 100 MB. But if you’re having 500 duplicates of those email messages, it’ll definitely increase your mailbox size from 100 MB to 150 MB. You might have thousands of duplicate items in your Outlook mailbox. You must remove Outlook duplicates to make your PST files handy, so that you can avoid Outlook corruption.

Clients Reviews

"After converting my large size OST files into PST, I found the duplicate data in the PST files. I tried to remove those duplicate data manually, but due to huge number of PST files, it was difficult to remove all of them. After all efforts, I’ve decided to use any duplicate remover and found this unique solution. I am very happy to use that. Thanks"
