Some libraries can accept incoming e-mail.
Here’s another great tip, although it’s not limited to Word, Excel, and PowerPoint 2007. This is a tip you can use with any e-mail program. However, this works only if the person in charge of your site has set up your library to accept incoming e-mail.
Here’s how it works. You attach a document to an e-mail message and send the e-mail message to a document library, and the attachment will get automatically added to the library, as shown here. To find out if your library accepts incoming e-mail, ask the person in charge of your site. If it does indeed accept e-mail, obtain the e-mail address of the library, and you’ll be all set.
