Hii.. I am using ANSI version of Outlook in which I have around 1.5 GB of data with attachments.  I thought some files gets corrupted can I see them? Right now I don’t want to upgrade my Outlook to Unicode. Is there is any way by which I can reduce PST files without upgrading to Unicode?

    You can easily reduce PST file size by dividing them into smaller parts by Date, Year, Folder and size. SysTools Split ST software is best utility for that.Download free version to check software reliability.

    Microsoft Outlook limits the size of older Personal Folders .pst files and offline folders .ost files to 2GB. If a new or changed item increases the size over than limit, you will not be able to use the .pst or .ost file. Even if you delete items from the server mailbox, the .ost file will not synchronize with Outlook 2003, larger PST files are supported. However, if you upgrade from an older version you need to create a new PST, the older PST format is not automatically converted or upgraded If the old PST won't open in Outlook you will need to repair it before you can convert it. Hoping this helps

    You can split your PST file. This will keep your PST file within limit and that too without changing your ANSI version.
