Place your curer in the notes/body field of the Outlook item (in the thumbnail example below, we are using an Outlook journal entry). Unless the item is an email, on the item menu bar select Insert/File and the Insert File window will open.
Use the browser to find the file that you would like to insert a hyperlink for then select it and click the drop down arrow to the right of the Insert button (lower left hand side of the Insert File window – see thumbnail below).
Select Insert as Hyperlink from the Insert button drop-down menu and you will see a link appear in the body of your Outlook item. If you click on the hyperlink, the file will open.
If the item is an email then you should select Hyperlink directly from the email Insert menu as shown in the thumbnail below:
The Insert HyperLink window will now open:
Use the LookIn drop down window to navigate to the shared drive, intranet or extranet where you have the document stored and then select the document from the list box and click the OK button. Your hyperlink will now appear in the email body.
The great thing about inserting Hyperlinks instead of the file itself is that you will always get the latest version of the linked file and a hyperlink takes up a lot less storage space in your Outlook Mailbox than an actual file.
