There are several people with my name at the company I work for. I frequently get email meant for someone else.

Worst was at another company where a person with the same name has just left, so they gave me that email address. Turned out he was subscribed to several Confluence pages for which I now received updates. But I didn't get his Confluence account, so I couldn't unsubscribe from those updates.

Couldn't you reset the password since you have access to the email address?

Might have been using company SSO.

SSO indeed. I forgot if it was ever solved before I left.
