smtp error

[mark_e_h]

Calibre can't seem to talk to my SMTP server. Setup is identical to Thunderbird and Outlook, but SMTP objects: 535 Incorrect authentication data

A call to my ISP was not helpful.
System is Windows 10, Calibre is 5.22.1 64bit, if any of that helps.
Encryption is SSL.

A log is below. Any suggestions would be appreciated.
thx,

Spoiler:

There's nothing we can do to help you. Your smtp server is refusing your user name and/or password. Either they are incorret or you need to enable one of the TLS/SSL options. I suggest you setup a free gmx or hotmail account and use that instead, there are one click buttons for configuring them int he calibre email preferences.
