Attaching files and documents to e-mail messages has become a standard method of communication. The advantage to sending or receiving a Visio attachment is obvious—to receive the document quickly. The disadvantage may be that the receiver must also have Visio installed to open it for viewing.
To send a Visio drawing document as an attachment with Outlook, follow this process:
From Outlook, start a new e-mail message.
Address the message appropriately.
From the Insert menu, choose the File command.
The Insert File dialog box appears.
Navigate to retrieve your Visio file.
Click the Insert button. The Visio file is inserted as an attachment to the e-mail message.
