Outlook.pst File Remains Same Size Even After Deleting Emails. Why?

I’m in trouble with the error “deleting emails does not reduce PST size”. Let me tell you what I did. I am using Windows XP & MS office 2007.

I have 1 PST file (PST_10) which is 3.7 GB in size. I closed my PST file from Outlook & then closed Outlook too. I traverse to the folder where the PST is placed & had made the copy of it & renamed as (PST_11). After that, I opened Outlook & opened my new PST file. Following this, I shift deleted my emails which were there (since June 2011). I did the same procedure with each folder in my PST file. Then I again closed my PST file as well as Outlook.

When I went back to the folder where the 2 PST’s were stored, I saw the size of the new one has not even reduced a bit, rather the size was increased by few Kbs. Even the renamed option was disabled & I was not able to rename my PST file.

My main motive to create a new PST file was to reduce the size of it, but even after the deletion, the size remains the same. I am trying to compact the files. But the files are taking so much of time for compaction & I don’t know how much time will it take more.

If anyone knows what is exactly happening, please let me know. If nothing will work, then please suggest me a suitable method to start a new PST to store my emails.

Thanks for your support!

Hi, AllnnThanks for the techniques which you all have shared. I am able to move my other folders of Outlook easily but my Inbox is very bulky so it is consuming a lot of time. Even the Outlook is creating an issue while opening. As my Inbox include so many emails which are useful, Please suggest me methods so that I can truncate the files into 3 Folder or many to manage my inbox data easily. nnThanks. n

Hi Dexter, nnI think you should use a third party utility i. e. a third-party tool Split PST software to break your files & folders for easy management. I also tried this tool to break PST files & found Satisfactory results to divide oversized Outlook PST files into smaller parts. This tool will also help you to divide your inbox files into multiple parts.
