Working in a Worksheet that has protection on
 

I am working on an excel spreadsheet in which I wish to protect some
information, and stop users from changing certain information. When the
spreadsheet is populated by the user, I want them to be able to do at least
three tasks:
1. Insert and modify comments on various cells
2. Create an MS Office Outlook Task when the workbook is protected (ithe
icon appears, although it is greyed out and inaccessible)
3. send the amended populated spreadsheet to a selected mail recipient.

I am thinking is that if the sending of information is allowed via e-mail
(Outlook), then why is the creating a task option (also part of the Outlook
Suite) not available.

I would truly appreciate input on this one please - at my wits end and I
think I have tried everything!
Many thanks
