I started using Outlook in May 2006. I have a big pst file, about 3.6
gigabytes. I archived and am compacting, so that should work. My question is
about attachments, are they part of the pst file size? When I get an attachment
I want, I click on save as and save it outside Outlook. However, does the
attachment then still remain in Outlook? Is there a way to delete attachments
while still keep the body of the emails?
Attachments are most definitely part of the PST file size. In fact, I’d
hazard a guess that attachments are the number one cause of PSTs getting as big
as they do.
And 3.6gig is a pretty big PST.
I have some cautions for you, and some steps you can take.

All attachments and embedded graphics and formatting are stored as part of
the individual email within which they happen to appear. So if you get a 5 word
email message with a 100 megabyte attachment, that’s a single mail message
that’s over 100 megabytes in size. Actually, because of the way that an
attachment must be encoded as text, that 100 megabyte file might well take up
120 megabytes or more of space in the email message, and as a result in your
Saving an attachment doesn’t remove it from the message, and hence does not
remove it from the PST.
When you save an attachment, all you’re doing is:

You haven’t changed the email at all. All you’ve done is made and saved a
copy of the attachment.
Which, by the way, is also what happens if you double click to run or
execute the attachment – it’s decoded, a copy is written to disk, and that copy
is then run or otherwise acted on.
You can delete attachments from the email you’ve received, and therefore
from your PST.
Since the attachment is part of the email message, what you’ll do is modify
the message. Open up the message containing the attachment you want to remove,
right click on the attachment, and click on Remove. That’s all
there is to it.
After you’ve removed a few attachments, you won’t see the PST get smaller
right away. You’ll either need to wait to let Outlook compact the PST itself,
or force compaction manually.
Now, I can’t let that “3.6gig” go without comment. That’s a huge
PST. I hope you’re using the latest version of Outlook – or rather the later
version of the PST file format – since older versions will have problems when
PST’s exceed 2gig. Even if you are using the proper version, that big a PST
makes me very, very nervous. I would absolutely make sure that it’s being
backed up regularly, and I’d seriously consider breaking it into several
