Hi, non-techie here would appreciate help. Have just had emails from Microsoft saying that after September 16 they will no longer allow third party email systems to access hotmail. Gave instructions to change incoming and outgoing server seettings to 'OAuth2'. I tried. Can change incoming, but then it gives me some kind of error message saying Thunderbird cannot support... Cannot change outgoing at all- the OAuth2 option is simply not there. I am apparently using TBird version 128.0esr and seem to receive regular updates. I am now baffled. Any guidance appreciated, thank you
