Microsoft Outlook PST file size limit

Microsoft Outlook limits the size of 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.

Outlook 2003 allows .PSt files of up tp 20 GB.
