Emailing from Libraries
Avoid sending documents through email; emailing documents creates multiple copies that are difficult to keep in sync. Instead, send links to documents.
To send a link from SharePoint:
On the document's Edit menu, click Send To → E-mail a Link, as shown in Figure 8-8.

Figure 8-8. send links, not copies!
When SharePoint inserts a link in an email message, it encodes the URL in this way:
http://usingsharepoint%2Ecom/home/Shared%20Documents/ch02.doc
That link only works if the recipient receives mail in HTML format. If the recipient uses plain text, edit the link to use periods in the domain name before sending:
http://usingsharepoint.com/home/Shared%20Documents/ch02.doc
If you don't want to go through that hassle, use this procedure instead:
Right-click on the document in SharePoint and click Copy Shortcut.
Create a new email and paste the shortcut into the message. This technique creates a link that works in all email formats.
