    Cannot get the access token when setting up FluentSMTP with M365.
    The following error shows up after the M365 login screen: 

    AADB2C90090: The provided JWE is not a valid 5 segment token.

    Any help is much appreciated. Already tried everything I could think of… Thanks in advance.

    Hello there,

    Would you please check if the account you are trying to use in Fluent SMTP has proper permissions?

    Outlook has various subscription types and not all of the account have permissions to send emails.

    Thank you

    Double checked the permissions. It’s not a shared mailbox, and has all the required rights to send e-mail. Just not to send as ‘someone else’. Is this necessary?
