I am getting a "Data Not Available" error any time I click on a link in a Salesforce email. These are emailed reports and Chatter notifications where I was @ mentioned on a contact, etc. I know for a fact that the records aren't deleted as I can access them via the Chatter tab or global search. I have another user who receives the same report, and she was able to open the link. What gives? Has anyone else had this issue? For what it's worth, I'm an admin and use SSO but have the same issue even if I'm already logged in to Salesforce. And this issue just began. It's worked fine for 3+ years!
