Ensure that the phone type used for emails in The Raiser's Edge is 'E-mail' not 'email' or 'e-mail'. Otherwise, Outlook will not recognize it. If this does not resolve the error:
 
     
    • Temporarily grant Power User rights to the user
       
    • Create the com add-in
       
    • Remove the Power User rights.
       
     


    Note: Consult your IT department or network administrator to perform the above steps.
