Outlook can become unstable if the PST file is too large. There are several ways to save and archive old emails and folders.
I've having problems with my Outlook PST. I think part of my problem could be too many files and folders. I'm a recruiter and I save endless messages in folders in Outlook as a running documentary of each search. I've not been able to figure out a way to transfer this data out of Outlook. The only suggestion to date has been to copy/paste each message into Word. I have 671 folders and 15,353 items in Outlook. So copy/pasting into Word might take months. If you have any other suggestions, I'd appreciate it.
In this excerpt from Answercast #71, I look at ways to manage large Outlook PST files.
Yes, I actually have a comment and a suggestion.
To begin with, even though those numbers feel kind of large, 671 folders and 15,000 items, that's actually not that huge. I'm convinced that I have way more: certainly in items. Folders? Yeah... I suppose it's a larger than normal - but it's not a number that concerns me. I'll put it that way.
What might concern me would be the overall size. In other words, if those were 15,000 small email messages, that's very different than 15,000 huge email messages. So that's something else to consider when you're looking at the PST as a potential source of problems.
Now, my suggestion in general is not to deal with this Word thing. You're right; that's unworkable. Instead, create another PST.
What most people don't realize is that Outlook can easily handle multiple PST files at the same time.
What you do is you use the "File menu." Then there's a "Create New." A data file is what you end up wanting to create. You get to specify the location of the file, which can be any location on your computer of your choosing. Then it creates a brand new Outlook data file, an Outlook PST file. It will show up in the navigation area on the left hand side of your Outlook screen with a set of folders.
Now, all you need to do is drag and drop whatever you want out of your existing PST into your new one. Yeah, that will take a few minutes to copy, depending on the size of the email messages, but it's a very handy way to break things up.
What I was doing, when I was using Outlook as my email client, is I would create a new archive PST once a year at the end of every year. So I would have, like, 2005.PST, 2006.PST and so forth. I would copy over, or actually move over those things I wanted to save from my regular PST, from my day-to-day PST, and archive it in those separate PSTs.
Then it's totally up to you whether you even need to have those PSTs open. You can always do a "file open" on them later, or you can have them open all the time. What's important is that you move things out of your existing PST. In other words, you would take a bunch of folders for, maybe, some of the searches that you don't expect to ever have to look at again.
You simply drag and drop those into the new PST that you've created, delete them from the old one.
After you're done with that process, after you're certain that all of the email is where you expect it to be, then make sure to right-click on the original PST in Outlook and select Properties. Somewhere in there is the option to "Compact the PST."
Much like the file system, when you delete mail out of an Outlook PST, the space isn't actually physically recovered. It's just marked as being unused. The compaction process will actually make the physical PST smaller, and in the process it actually should speed up Outlook's access of that PST.
My guess is that I don't know what kind of exact problems you're having with
Outlook but if they're PST related, spreading the load over some number of PSTs
and keeping your active PST smaller will probably go a long way to making
things a little bit more stable for you.
