Suddenly my email @outlook.com cannot synchronize anymore

suddenly my email @outlook.com cannot synchronize anymore.

i have version 1.16.0-5339a49f, on windows 11 pro french 25H2 2600.7171.

my cpu amd ryzen 7 5800x.

chipset amd x570s, 64 GB ram.

i have @hotmail.com account that is working still fine.

i have other accounts (no microsoft related, andno google related, using imap) that are still fine.

only my @outlook.com stopped working.

i have a permanent red pop up on the lower left corner stating that “a mistake produced during synchronization of outlook.com, try again”.

and everyt time i try again, the pb is same.

i tried to reconnect my account, it reconnects on the webpage (login, password, otp), but not in springmails.

i have seen a brief message telling me that technical support will be notified and i have to wait for a solution.

but i prefer to write here.
