Server reports ‘unauthorised’

[Sib]

Hello,

I am currently using eM Client Personal (10.3.1738) on a desktop computer and on a notebook (both Win 11, 24H2 - 26100.3915).

On the desktop computer, I am receiving emails from all email accounts (with the same provider) without any error messages.

On the notebook, however, the same email accounts with identical (!) account settings (imap/smtp) are received, but only with continuous warning messages (server reports ‘unauthorised’).

What could be the cause of this?

The error messages are also annoying because they have to be clicked away every time in order to continue working.

Thank you in advance for your feedback.

Best regards,
Sib

Hello,
to prevent the error mentioned in this thread from occurring, the CardDAV and CalDAV services should be disabled in the account settings (at least on a trial basis).
