I recently transferred my outlook 2003 to a new computer. Everything worked
fine till last week. Now I am getting "Out of disk space" error.

I have already emptied old/junk folders, created new .pst file and other
mailbox cleaning I could do. My inbox is @4GB.

I have 2 GB RAM & 320 GB HDD. Windows XP, Outlook 2003.

Help appreciated.
