Exchange account from Ubuntu "Online Accounts" no longer works
I have one Exchange account that just stopped working all of a sudden (another still works, but I think it's connecting to an older version of Exchange). Specifically, I am getting an error in Online Accounts that authentication has failed, and evolution stops syncing the mails.
I'm seeing this in the logs:
Sep 26 21:19:27 rk1424-XPS-13-9350 gnome-control-c: goa_ews_client_autodiscover() failed: 2 — Error resolving “autodiscover.mail.gc.cuny.edu”: Name or service not known
This particular account worked for quite a while before this problem.
