Both OL2003 & 2007, using the newish unicode format pst, data file, can cope
with files upto 20gb

Scanpst.exe may be located in C:\Program Files\Common
Files\System\MSMAPI\1033 folder, in any case a search would locate it,
simply run it on your data file - sometimes several 'runs' helps.

In OL help look up Archive

I have been saving my company e-mail in personal files for some time. I had
a problem wi Outlook 2003 where I could not update my calendar without
getting this error message " Could not complete the operation.One or more
paramater values are not valid."
1- I now have Outlook 2007 and am having the same issues. I don't
remember how I did the SCANPST.EXE thing, buit it worked. Anyone know
the process fopr this?
2- Also my PST files are showing up as being over a gig, I have been
told the files can go bad if they are too large. IS there a good safe way
to split these up or ask the system to start putting them in a new place?

Best,

Gregg
