Outlook 2007 PST limited to 2GB, not 20GB as advertised

    Question

  • I'm running XP (32 bit) with Office XP. Uninstalled Outlook XP portion of Office XP. Rebooted. Installed Outlook 2007. Opened Office 2007. Imported email from Outlook Express 6. Import appeared to complete, but pst file stopped growing at 2GB. Lot’s of emails not imported. It appears that Outlook 2007 honored the Outlook XP pst file size limitation of 2GB, not the 20GB limit advertised for Outlook 2007. Any attempt to delete an email, create a calendar item, return error that pst file has exceeded 2GB limit.

     

    Uninstalled Office XP entirely. Uninstalled Outlook 2007. Moved the PST file to another folder. Rebooted. No Office products installed on this machine, now. Installed Outlook 2007. Added the registry entries per http://support.microsoft.com/kb/832925

     

    HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\12.0\Outlook\PST

     

    MaxLargeFileSize, REG_DWORD, 20480 (20 GB)

     

    WarnLargeFileSize, REG_DWORD,   19,456 (19 GB)

     

    MaxFileSize, REG_DWORD, 2,075,149,312 (1.933 GB)

     

    WarnFileSize, REG_DWORD, 1,950,368,768 (1.816 GB)

     

    Imported email from Outlook Express 6. Same problem as before. Import appeared to complete, but pst file stopped growing at 2GB.

     

    Any ideas?

  • Based on your description, it appears that you are using the PST file that was created in an earlier version of Outlook.  If this is the case, then this is why you can't push past 2GB.  Outlook never... ever... just can't do it... upgrade the PST file to the new layout.  You must create a new PST file and copy/move/import your items from the old PST to the new.
     
    Oh, should warn you about hard drive format.  You can only reach 20GB if the PST file is sitting on NTFS formatted drives.  FAT and FAT32 formatted drives will limit the size of the PST because these file systems don't permit files to grow beyond specific sizes.

  • Sounds like you are using an ANSI pst format which does have a 2GB limit.  If the pst is Unicode (which is default in Outlook 2003+) then you can get to a 20GB limit.  I would create a brand new pst and drag your items over to the new pst.  More info:

    Or convert the PST:
