I have the same problem described in https://forums.xfinity.com/t5/Email-Web-Browsing/Emails-with-Embedded-links-to-files-on-Google-drive... (now locked) but the responder there was confusing Google DRIVE with Google DOCS and the recommended solution doesn't exist for Google DRIVE.
In a nutshell, if I make a link in Google DRIVE and past it into a new email in Outlook for my Comcast account and send it, the email vanishes. Not in Junk, not in Trash, no error, nothing. Just gone.
The answer in the post above said you could email the link from within Google but Google DRIVE has no such option that I can find.
I want to share a big file with about 20 people. Emailing a Dropbox link works fine, why not a Google DRIVE link?
