pst too large

My pst files are apparently way too large.  I was reading a comment by one of the other experts and he said 2 gig is the danger zone.  I appear to have almost 14 g.  Some is archived and some is not.  My question is:  how do I get the size down.  I think there are a lot of duplications.  I run a business that is heavily email and am reluctant to totally delete many of the emails even though they are several years old.

To remove duplicate emails you can download a duplicate email remover. There are several on Google that you can try out. If you have many duplicates, this will assist with the size.

That being said, a  14g pst file is enormous.

You also might want to sort the emails by file size ( in deleted items, inbox, sent, drafts ) and delete the ones that are like 200kb +. If you need to keep those large emails, save them to your desktop in a folder you create for emails.

This will greatly reduce the size, but there is some tedious manual work to do.

You can create new pst files and move the old emails to several archive pst files that don't have to be loaded into Outlook everytime you start it up. Wihile working offline => file "work offline" create pst files by saying file => new => Outlook Data File. Then copy the emails from your main pst file to the archive file.once the old emails are copied over you can close the file so that it doesn't open with outlook everytime you access your email. right click the file and chose close.

This file can be opened at anytime to give you access to the archived email by saying file open outlook data file. I would name them something that is relevant to the emails they will hold.

For outlook to opporate an archive .pst file can be larger than 2 GB but your default .pst file must never go over 2GB or your email will begin to malfunction.
The 2GB PST file limit is only an issue up to Office 2003. Office 2007 removes the 2GB limit. However, as the file gets larger, you will find that access is slower.

14GB is the largest that I've seen, with 3-4GB being more typical for a single user accumulating email over several years.

Have you tried to simply empty the trash and compact the file?

Alternately, you can create a new PST file and copy the relevant email to it. Archiving (or deleting) the old PST file and then selecting the new PST file as your default for mail delivery.

2 GB limit was for ANSI PST files which were created by Outlook 97, 98, 2000 and 2002. With Outlook 2003 , 2007 and 2010 the PST files are UNICODE PST files which supports 20 Gb or more . The onlynthing is that the performance detoriates. I have seen the PST file of more than 30 GB working fine...but it is one of the very rarest scenarios.

What i would suggest you is to archive the emails yearwise into multiple PST files. Also there could be many emails in sent item folders which you do not want to keep. You can get rid of these. Empty the deleted items folder.

For more information on PST files please see the following KB articles:

You may experience performance problems when you are working with items in a large .pst file or in a large .ost file in Outlook 2007
