I have a google account. Someone sent a link to access a google doc to my email email@example.com. I added firstname.lastname@example.org as an alternate in my google account. It still does not allow me to access the google doc. It says my google email doesn't have permission.
Isn't there a way to add a non google email to your google account and allow the non google email to access google docs? After all, the google doc was sent to email@example.com and not the gmail email.
