[sylpheed:37334] Microsoft (Hotmail) and how you lose access to mails through an IMAP mail client when you switch to the stupid OAuth2

[Javier]

Hi there again :)

Today was the day, after a very long summer with several suffocating
heat waves that left me with almost every day away from the computer;
and after make a backup of mails, I have tried OAuth today, and,
without any surprise... it didn't work.

The worst is that once you try OAuth, any other authentication method
gets disabled on the server for your account. Yay!!

But, funny, I still access it through POP3 XD.


Good news is it does work on Windows 7... I guess, because I get the
following error:



> [23:22:52] IMAP4> 2 AUTHENTICATE XOAUTH2
> [23:22:53] IMAP4< +
> ** LibSylph-WARNING: [23:22:57] Could not get OAuth2 token.
>
> ** Could not get OAuth2 token.
> [23:22:57] IMAP4> 3 LOGOUT
> [23:22:57] IMAP4< 2 NO AUTHENTICATE failed.



I don't get the reason of not being able to get the token :? All is
fine on the Microsoft account permissions, despite Sylpheed appears
as unverified.

I even disabled the firewall or anything else :-? And still I don't
get it. But the page served by Sylpheed to the browser tells all is
fine.

I had hopes as the Microsoft docs tells that with curl only was
possible without a browser:
https://learn.microsoft.com/en-us/graph/auth-v2-user

But the whole process (rely on an external browser) and all the
hassle... Nah, this is not for me.


The purpose of a desktop mail client just gets defeated with OAuth.


I'll give a try with Seamonkey in the next version, that they say it
will support Hotmail/Outlook with OAuth and, if it doens't work
either, I just give up of this OAuth thing and of my old mail
accounts.




By the way, how the heck do you deal with the 3.7.x and above flat
interface? That is the main reason I never upgraded from 3.4.3. I just
can't deal with it. Also the small headings, the very ugly font
rendering. Argh.

How can I change this?


Regards.
