Correction! My advice yesterday was wrong. I was just checking my Sent file in my Notes account, to delete large files, and the test message I sent myself yesterday, where I attached the shortcut to a large file, had THE FILE ITSELF attached to it! To do just the Link, you may have to put the file into something like Filenet - I have their Content Services product, and it has a feature in the web client that WILL create a Notes Email with a link to the file you've selected. We use that feature heavily here - our Fire Department puts training and policy memos for the troops (over 500) to read, and then sends an email to the whole department with the link to the document. The same cautions apply - the folks receiving the link must have enough privileges to be able to open it if they drilled through without using the link.
