Should not be more than 1.8g after that you can start having issues. As far as how many pst files you can open, Well what is it that you are trying to ask here.
A pst file contains all the info,email that is in your Outlook. If you are trying to ask on how many emails can you have open at any one time then that is another story. So what is it that you are trying to ask here with the pst file

How large can a 2003 pst file get and still be safe?
How many pst files can be open at the same time?
Thank you

The pst is still to large.
Either archive again, changing the archive date settings, or create a new
pst and move data to this. Then compact again.
An early version pst can go south at 1.6gb, remember also the size problem
also effects an archive file, which is just another pst.

One of my users was having problems with their email (Outlook 2000),
recieving emails.
When checking, I found his pst file to be 2,097,136 KB.
I was able to archive sent items (along with attachments), that created an
archive pst file of 438,233 KB, but the original pst file size hasn't
changed.
Why is that?
I tried compacting it, but no luck.
They appear to be able to send & recieve email now, but I'm concerned
about the size issue.
Any advice appreciated!
