I've unwisely allowed my pst file to get to a size of approximately 372 mb. It's been all I could just to get it to open, and now I can't seem to reduce it in size because the file can't be accessed, although all the email does eventually display. Also can't export it because of some kind of Outlook problem that requires me to run setup, but I can't run setup because of some kind of windows problem. Also tried splitting the pst file up with a splitter utility, but I get a data stream error. Also can't transfer the file over a network to another computer or copy it to a CD or even copy it to another location on the same hard drive. Any suggestions?
