I believe what you are reporting is that when the user clicks on the quick link for Notebook from the Discover Page, they witness a dialog warning "Database Notebook cannot be found" and the option of entering the location for that file.
This result can easily be reproduced in the following fashion:
- a Notebook application or file (nsf) can be geneated in two ways (by default is saved in the local Notes\Data folder):
(1) using the quick link or icon from the Discover Page
(2) from the Notes Workspace HOME page, use File/Application/New/ , select the Notebook template and name the application Notebook.nsf
- by using the link, this will update the local Bookmark database to point to the generated file (location)
- if a user happens to move, rename or delete the local Notebook.nsf file, a subsequent attempt to click on this quick link will result in the dialog warning above
A simple workaround you can try to resolve this dialog warning is to either use the second means above to maually generate that same file and place it within the local Notes\Data directory for the Cient to access, or find whether the file may have been moved outside of this directory and move it back to Notes\Data folder. You may want to restart the Notes Client after this.
