Why do I receive e-mail notifications from groups I have not joined, or on products I do not care to follow. I have gone through the notification portion of my profile to be sure everything has the correct settings. However I still get e-mail notifications on say for example Enterprise Vault. I really don't work with Vault at all. It would be nice to know where these are coming from and how to stop them.
I looked at your Notifications, and you are signed up to receive e-mails for more than 100 discussion thread updates, as well as a few group updates. I have Unsubscribed you from Group Updates. You still have 102 notifications coming at you. I can change any or all of that if you like.
GRH probably stopped the majority of your email by unsubscribing you from the Partner Group notifications.
Users who are members of the Partner Group can (and sometimes do) tag forum posts from various and sundry parts of the community as being relevent to Partners. That's why you're getting notifications that don't seem to be relevent.
