I have saved an email as a message file (e.g., MyEmail.msg). In the same
folder where this file is saved, I have an Excel file which I periodically
update. When I open the message file, I then attach the Excel file. But the
message file opens to my default folder for Outlook (e.g., My Documents).

Is there a way to reset the default path for this message so that when I
insert the Excel file the dialogue opens to the folder where the Excel file
resides (My Documents/folder/)?
