Add URL in notes startup for all users through policies or programmatically.

You can start a particular website in the web browser when the Notes client starts.

For that, you need to add the URL in "startup" under Open list - More bookmarks.

Refer: How do I create bookmarks? --> https://help.hcltechsw.com/notes/12.0.0/ja/client/fram_creating_bookmarks_t.html

Example:

If you want to add a yammer site at Notes startup. Open the yammer site in an external browser like Edge or chrome. Drag the URL from the external browser & drop it to Open list - "More bookmarks" - "Startup" in Notes Client.

You can perform the above steps for one user.

There is no option to add a URL in notes startup for all users through policies or programmatically.
