I received an email re outlook.com saying that I needed to start using Mail in Windows 10 before 30 June 2016 and that support for windows live mail would stop from then. I've started using Mail and have a Hotmail account working and have my contacts, but a bigpond.com account won't work. When I try to sync I get error code 0x80072746 re a problem downloading messages. Also the change mailbox sync settings is not available for this account.
