Third-party email clients, like Outlook and mac Mail, use either POP or IMAP protocols to connect to your Yahoo Mail account. These apps need a lot of things to align perfectly in order for them to work properly with an email account. I had the same problem! I have a TM 1 tb and a WD usb drive connected to it. When I open movies through the WD disk I didnt get this message, but when I open movies through the TM hard drive Ive got just this message.

Someone just introduced this to my attention today: Outlook 2016, when it desires to prompt for consumer credentials to authenticate (if I delete my Exchange keychain admittance for instance), automatically floods in the user's email deal with in the 'user title' field rather than their usérname. This will result in authentication to fail for on-prem Exchange if the user simply enters their password.

They require to edit the industry to be their username. Provides anyone else seen this? I believe this is definitely how O365 authenticates and this is usually a insect centered on that. We'll need to train customers to do this themselves when they have got a security password switch or additional prompt.
