Links in Cells
 

I use a spreadsheet every day to keep updates from around my European
colleagues, these updates are always emails in Outlook. Ideally I would like
to do something like 'insert comment' but have it like a link to the email.
The reason is that if someone quesries and update, say 2 weeks later, I have
to backtrack through many hundreds of emails.......I already use MS LookOut
but having it in Excel would be better.
Thanks
