    Group imap account not receiving emails with Outlook Integration

    Hi, Our group imap account stopped receiving emails spontanusley in mid of july. Before everything worked just fine.

    If I check the IMAP connection it fails saying Error 500: cannot login, user or password wrong, even though I can guarantee its correct. The same credentials are put into SMTP, sending the test email here works.

    When I try to connect (reconnect) the outlook extension, login with the required user and accept the app permissions I get Error 500 - Could not get access token for Outlook.

    Nothing was changed on the app permissions side or the email account. Only thing which was changed since three running years is the rotation of the client secret.

    We are on the latest espocrm version with the latest outlook extension.

    I already tried restarting, made sure the permissions are set, removed the email setup and readded it again.

    Has anyone else encountered this issue, or does anyone have suggestions on what else I can check or try?

    Greetings, Lukas Klepper,

    To investigate this issue further, please follow these steps:

    - Enable Debug mode: https://docs.espocrm.com/administrat...ng/#debug-mode.
    - Reproduce the error.
    - Provide the EspoCRM error log. EspoCRM log files are located in {ESPO_ROOT}/data/logs/ directory. Most errors are logged there.

    The log file can be zipped and attached in reply.
