In order to save space and be more efficient in creating tasks, I love to include a link to a network document or network folder that I have to do as part of the task. I tried a bunch of ways to get a link to a network resource in my outlook tasks note. I found a method that seems to work all the time including dealing with spaces in either the path or document name. Place brackets around the path.
To create a link to a network server named "bigserver":
\\bigserver\directory\this is the document.doc
<\\bigserver\directory\this is the document.doc>
Outlook will then create a hyperlink to it and either open the file in the associated program or open Windows Explorer to the proper directory. Why this was so hard to find -I don't know.
