I once was the third person of my firstname, lastname combination at a company, so I got firstname.lastname02@company as email address. At some point I was in contact with an admin who noticed that the original firstname.lastname@company wasn't working there anymore, so he thought he'd be nice and give me that email address now. That was a terrible idea. Apparently, the original firstname.lastname was watching a couple of Confluence pages so he'd be notified when they changed. Those emails went nowhere because the address didn't exist anymore. But now it suddenly did again, so I started to receive all those notifications. I visited those pages to see if I could turn the notifications off, but they were controlled by the original guy's Confluence account, which I had no access to of course.
