When I go to Settings > Office 365 > Personal Info, I can edit the info and update my Alternate email.
However, one of our employees had their personal email (which they were using as their Alternate email) hacked. So, they want to update it to their new alternate email, but when they try to go to the Personal Info section, there's a blurb at the top that reads "Why can't I edit?" and it instructs them to "contact IT department."
Well... I'm the closest thing to an IT dept. we have, I have Admin rights, but when I go into Edit User, there is no where to put in the alternate email address. I could add an alias, but that's not used for resetting passwords.
