    .pst File Size (Outlook 2003 (11.8169.8172) SP3)

    I am a brand new member and apologize if this is covered elsewhere.

    My outlook.pst file has just gone over 1GB, and my archive.pst (everything older than one year) is .8GB. There is a definite slowdown at Outlook startup and closing. I am concerned about where this is taking me. Can anyone offer a solution? I am not concerned too much about backup. I handle that, but I am concerned about performance.

    Thank you.

    Tom

    If your PST is the Outlook 2003+ version Unicode type, you are not in danger of losing data through file corruption.

    You could try running scanpst.exe (the inadequately named "Inbox Repair Tool) on the PST to see if it removes any structural problems, and that may help with loading speed. Next you could force a compression of the PST (right click the PST folder root, select Properties | Advanced | Compact Now), but since Outlook compresses in the background, it's not likely to make much difference. You could get more aggressive about archiving old records so that your PST is smaller, or you could try making new PSTs and dividing your data up amongst them in some structured fashion.

    If you are on exchange server and your PST is on the network, you could move it to the local hard drive, if company policy permits.

    Thank you John. I had never heard of scanpst, and ran it on both the Outlook and the Archive files. It found problems on both and I got a nice little "Repair Complete" window on both files, so presumably the problems were fixed. See log files attached. (Oops, I could only attach one, so attached the Outlook file.) I have renamed both .txt since .log files are not in the allowed list below as I post.

    I then compressed the two files, but no size change resulted.

    How do you feel about an Outlook file of 1GB and an Archive file of .8GB? Are these too big? I wish I could understand what you meant when you said "or you could try making new PSTs and dividing your data up amongst them in some structured fashion.". That sounds like what I would like to do. In fact I rather like Thunderbird's having a separate file for each e-mail folder. Wish I could do that or something in between.

    Thanks again.

    You can select File | New | Outlook Data File to create a new .pst file. Choose the Office Outlook Personal Folders File (.pst) format, not Outlook 97-2002 Personal Folders File (.pst) unless you need to be able to open the .pst file in an older version of Outlook.
    You can then create folders in the new .pst file, and move items such as e-mails from your 'main' Personal Folders File to the new one.
    You can create multiple .pst files this way, and organize them in a way that is useful to you - by project or by year, for example.

    See How to create a .pst file in Outlook 2003 for more info.

    I don't think a 1GB PST is egregiously large, but it will take Outlook longer to load a large PST than a small one.

    Hans has already covered the concept of splitting up the PST into groups of like items. At work I use 5 smaller PSTs; one general, and 4 according to groups of business type. Outlook is designed to work with multiple PST files, though in a standalone setting (as distinct from Exchange Server setting) one must be primary for message delivery and for Contacts, Calendar, Tasks, Notes, etc, that is, it must contain certain "default" folders.

    It would be nice if Outlook used multiple files like other mail programs, but:
    1. Outlook is much more of a Personal Information Manager, not only a mail client, and it's design leans much more to business use than personal use, and
    2. Microsoft elected to use a single proprietary file structure to hold data, for reasons known only to them (and that make it hard for Outlook data to interchange easily with other programs)

    Re: .pst File Size (Outlook 2003 (11.8169.8172) SP

    I can't believe it's been two months since I first started this thread. I am deeply sorry for not getting back to you good people who responded and offered help. Today, finally, I took your advice. All I can say is that I have been very busy and Outlook kept running, so there was no fire to put out.

    Today I created a second personal folder (.pst file) I call Secondary Folders. I clicked and dragged many of my folders to this new pst. When I was done, I realized this new set of folders was only 69MB, and that my real problem was that my primary folders - the ones I use most - were chock full to overflowing. My .pst file was still over 1 GB. So I changed my archive rule to say everything older than July 1, 2007 should be archived.

    So now thanks to your excellent advice, I have a primary .pst file of 770MB, and that's way down from where I started. Now my archive file is 1.3 GB. I wonder if I can do the same thing with my archive file and create a secondary one for certain mail folders? Then I could have 4 pretty balanced files in terms of size, all around 700MB.

    What do you think?

    Thanks again - very much - all of you who responded.

    Tom

    Yes, you can create multiple .pst files for archiving. You can specify to which .pst file items from a specific folder will be archived, in the AutoArchive tab of the Properties dialog of that folder.

    I was hoping that would be the case. Thank you very much.
