Outlook .PST File Size

    Question

  • I have been trying to fix two outlook .pst files (2003/2007) that are at or very close to the 2gb capacity. I am not able to move or delete any of the emails that I can see out of the pst files. Please review all of the steps that I have taken before you respond.

     1. Copy the emails into a new pst and then delete. I am unable to delete as the pst is at capacity.

    2. Move the emails to a new pst. I cannot permanently move the emails because I am at capacity.

    3. I used the oversize pst and ost crop tool (  http://support.microsoft.com/kb/296088). I trimmed the file down to 1.7gb and ran it through the scan pst tool. When reading it back into outlook it said that I was still at capacity even though I removed 0.3gb.

     4. I have also opened the .pst files on different computers both before and after cropping with no success.

     5. I have also changed the registry settings with no success. (http://support.microsoft.com/kb/832925) At this point nothing seems to work. Does anyone have a way to resolve this? I have a feeling that since the at capacity error still appears after cropping the file that the pst is encoded to think that it is at capacity when it is not and Outlook cannot get past it. Is there a way to 'crack' the pst? Thank you in advance for any help that you can provide.

  • Looks like you've done quite a bit of research already. i've had this problem recently. ultimately, what did it is upgrading outlook to the newer build (i think it was from 11.65xx.xxxx to 11.82xx.xxxx). for some reason the earlier builds of outlook would not read these "oversized" PST files that were created under 2002/2000/97 PST format (i.e. ANSI PST), regardless of what the registry limits are set to. with the newer build of outlook, it lets you at least copy/move the contents of the ANSI PST file into a newly created (2003 or 2007) UNICODE PST file. once you do that you are home free - keep everything in 2003 or 2007 format and you have up to 20GB or 50GB of max size respectively.

    If this doesn't work for you  then you may try to repair your pst file. And then again import it into outlook. To do this, use ScanPST from Microsoft. Here you can view more details how to use it. https://support.microsoft.com/en-us/kb/272227

     If that doesn't help you then try to use Recovery Toolbox for Outlook. This 100% should help. Success.  https://fixpstfile.recoverytoolbox.com/

  • Factually minimum size of Outlook 2003 and 2007 PST file are 10 and 20 GB respectively. So, if you are getting an error message or you are not able to perform desired task (like moving emails), then there is a possibility of PST file corruption. The simplest way to fix such a problem is repair Outlook PST file using, Repair PST File Tool. You can avail this tool on this link: http://www.repairpstfiletool.com/

  • Well you have try many methods. I want to suggest you another method to reduce size of PST using clean up tool

    •    Select the Clean Up tool from MS outlook and then choose Archive Option
    •    Then Select Archive this folder and sub folders
    •    Select data from mailbox to move
    •    save the new .pst file to a new folder
