Vicki Yes you will be able to open it, the size limit of an old PST file is 2Gb, a PST that was created with Outlook 2003 has a size limit of around 22Tb if I remember correctly, but that only applies if the PST file was created in Outlook 2003, if it was created in a previous version of Outlook the 2Gb limit still applies.

What is the size limit for pst files in 2002 vs 2003?
