I know it has 2GB file size limitation on ANSII format of pre-Outlook 2003
PST file.

But, does anybody knows how many items can be stored in this format? And,
how about this limitation in unicode format PST?

Thank you~~
 
Outlook 97/2002 PST:

16,000 items per folder when large table support is turned off (default for
Outlook 97/2000)
65,000 items per folder when large table support is turned on (default for
Outlook 2002)

16,000 folders per folder when large table support is turned off (default
for Outlook 97/2000)
65,000 folders per folder when large table support is turned on (default for
Outlook 2002)

Unicode PST:
Unknown, but rumour has it at 130 million. My guess is that you will hit
performance limitations before finding the upper limit.
 
Thanks for your fast response.... =)

I'm thinking about a solution for my boss. His Outlook receive +1000 emails
per days because he is the "alternative recepient" for all mailbox in the
company.

I configured the "autoarchive" to move old items to other pst files. But
this solution makes confusing for the user as there has too many PST files.
He is using Outlook2000. The below is my proposed solutions for centralise
the PST files:

Outlook2000 + Attachment Sniffer
In some tests, it shows this solution can reduce the number of PST files and
enhance the performance. However, as you said, this version of Outlook is
unable to handle that huge number of emails. So, upgrade to OL2003 may be
better but the hardware have to upgrade too....

Can you think another solution to prevent from software or hardware upgrade?

Thanks,
Keith
 
What mail server software are you using?

Are you using Exchange server? 2000/2003? If so, set up another mailbox for
message journaling as per
http://support.microsoft.com/default.aspx?scid=KB;EN-US;Q261173&. Host your
own mail on the server & have all mail handled by Exchange alone.

Also, if you are using Exchange, don't use PST files for storage. Use the
mailbox folders on the server.
 
And your boss is also a busybody with nothing better to do than monitor all
emails received by employees?? And he gets the big bucks for that !!??

Maybe his full official title is "Chief Snooping Officer". But you know,
there is sometimes a need for that, honestly. Depends what kind of office
this is, whether employees are misusing corporate email, etc.... Lots of
Exchange servers are set up for journaling....

Exactly, set up a MACHINE to do this, not a person. I would find it
difficult to work under those circumstances. AR bosses are the worst.
