    Hi Team,

    I'm trying to migrate EmailServer grom exchange 2016 to Office 365, already change server, ports, certs, but in my logs keep receiving error below:

    10:16:16.547 Std 20015 [MsgIn-1] <pop-client-teste> JavaMail Exception.

    In my researches it seem to relate to certificate, but it was generated as in documentation.

    Hi Debora,

    Could you share the configurations you did for the pop client section (WITHOUT SHARING ANY CREDENTIALS) just to validate the configurations that Microsoft offers for Office 365 Outlook? https://support.microsoft.com/en-us/office/pop-imap-and-smtp-settings-8361e398-8af4-4e97-b147-6c6c4ac95353

    Also, do you have the capability to check logs from Office 365 Outlook?

    I guess you don't need to configure a certificate because Office 365 is working with a CA-signed certificate so it should be secured by default (Opinion)

    Hi Debora,

    Try to change the following option pop-connection-security = ssl-tls then restart your Email Server and try again.

    Hi Debora,

    I mean in the [pop-client-teste] section you have created there's an option called pop-connection-security just modify its value with ssl-tls then restart your Email Server and see what will happen further.

    Do you have this working now Debora?  Did you also change the exchange-version option in the pop and smtp sections?
