Annoyance No. 2
Outlook's attachments make it massively bloated. If you regularly send and receive attachments, your Outlook .pst file can quickly become massively bloated. It's pretty easy for your .pst file to quickly get to 250MB or more, and I've known people whose files range up to 1GB and beyond. Among other problems, this slows down the speed at which Outlook loads and can lead to instability.
How to fix it: It's time to put Outlook on a diet. First, find out where the fat is. Outlook 2007 has a very useful folder called "Larger Than 100 KB." Find it underneath Search Folders in your list of Outlook folders. As the name implies, it lists all e-mail messages that are larger than 100KB. By default, they should be listed with the largest files first, but if not, click the Size heading in the folder until you get them listed that way.
Now that you can see the largest e-mails, start trimming. If you're like me, you'll be surprised how many of the e-mails with attachments you no longer need; delete those. If you need the attachment, but don't need the accompanying e-mail, save the attachment to disk, then delete the e-mail.
Remove unneeded attachments.
If the opposite is true -- you want to save the e-mail but not its attachment -- you can save space by either saving the attachment outside of Outlook or deleting it altogether. First, save the attachment to disk. Then open the e-mail, right-click the attachment and choose Remove. The attachment will be deleted from Outlook, but the e-mail itself will remain.
The attachment problem in Outlook is so notorious that a third party has stepped in with a solution that helps you cut down the size of your .pst files by removing attachments. The free Kopf Outlook Attachment Remover saves attachments from Outlook, stores them on your local disk and replaces the attachments with a link to the stored file. You'll be able to open the attachment as you would normally, except that Outlook will grab the file from disk, rather than from inside its .pst file.
The Kopf Outlook Attachment Remover.
You can have the program automatically go through entire directories, removing attachments and replacing them with links, or you can instead do it e-mail by e-mail. Note that in Outlook, it will look as if the file is still there -- you'll see the file icon as you normally do for an attachment. But the file is actually on disk, not in Outlook.
