Comment 15 for bug 1318834

After my most recent Ubuntu 16.04 LTS update (that required both an authorization password request and a post-installation reboot) the following message appears briefly in a small window in the top right corner of the screen after I sign into Ubuntu:

"Applications can no longer access your [@ATT.net email address] online account. Choose Online Accounts from the user menu to reinstate access to this account."

I looked at Online Accounts. All that currently appears there is my identification as administrator, my Ubuntu sign-on name (not an email address) and my password with a clickable button for viewing my sign on history.

Since the only thing unique about the referenced ATT.net email address is that it's the only email address issued to me by AT&T, my Internet provider that I only use for paying my monthly AT&T bill. I doubt that it has ever been listed with my Ubuntu sign-on name. So I have no idea if "Applications can no longer access your [@ATT.net email address] online account." should mean something to me. I'm not entering the AT&T address and password, and not identifying whether or not the account is Administration. I suppose I'll find out soon enough that's a problem. While I'm still a new user of Ubuntu, I'm not a neophyte computer user. It is vexing to encounter these situations. I'd welcome any explanations that clarify what I'm being instructed to do, if anything.
