DDE Server not acknowledging initiate filename
What happened
You tried to activate a DDE link in Notes® before opening the DDE server application and the file that the Notes® document is linked to.
Note: You also see this message if the linked-to file has been
moved to a different location. The link works only if the file is
where it was stored in your operating system when the link was created.
What you can do
Open the server application and the linked-to file; then try again to activate the link in Notes®. If the file has been moved, return it to where it was originally stored, or create a new link.
