I'm having the same problem as described in https://www.msofficeforums.com/mail-...rate-docs.html, but I've narrowed it down to Runtime Error '5852' Requested object is not available - it seems to be linked to .Destination = wdSendToNewDocument

I don't know anything about coding - I just needed a macro so I can split merged documents into separate files so I too would love to know how to fix this.
