You can already remove attachments in Outlook—but only one at a time, which gets to be a big waste of time.

Outlook Attachment Remover (clever name, huh?) does just what it says, but in addition to removing attachments from one message at a time, you can scour an entire folder clean. This works well if you are on an Exchange server with a mailbox size limit, or you just want to put a bit of spring back in Outlook’s step.

One of the problems with using Outlook to manage e-mail is that there is no easy way to manage attachments. Outlook is not a good place to store attachments. Outlook basically rolls all your information–e-mails, attachments, tasks, appointments, and contacts, into one .pst file. So the more attachments, the more data Outlook has to manage, and the slower it runs. I’ve heard that if your .pst file gets above 1 GB, Outlook borders on unusable. I’m not there yet.

You can remove attachments (after saving them to your client file, of course) one at a time, but this is tedious and inefficient.

There are a slew of add-on programs to help with this. Can anyone recommend a few to try to start? If not, I am going to start plowing through them, one by one.
