Hi, I’m quite new to CloverDX and simply try to use an EmailReader but it doesn’t work.
I used the [EmailReader | CloverDX 6.3.0 Documentation](https://doc.cloverdx.com/latest/designer/emailreader.html#id%5Femailreader%5Fexample%5F02) to create the job on a 6.2.0.14 Designer.
The job kind of starts but finishes with an error I just don’t understand.

Hi Martin,
The error message indicates that the server (Microsoft Office Outlook IMAP Server in this case) dropped the connection from the client (CloverDX). I dare to presume it was because you tried to connect by using SFA (single-factor authentication, i.e. username and password) which is not something Microsoft allows by default. As a matter of fact, SFA might already represent a deprecated option in the Microsoft cloud environment.
A recommended way to go here would be to create a valid OAuth2 connection (MFA - multi-factor authentication) to the Microsoft IMAP server (as described here: [https://doc.cloverdx.com/latest/designer/oauth2-connections.html](https://doc.cloverdx.com/latest/designer/oauth2-connections.html)) and use that connection in the EmailReader component (“OAuth2 connection” property instead of “User Name” and “Password”).
If you stumble upon any issues while establishing a valid OAuth2 connection to Microsoft I’d suggest logging a ticket to CloverDX product support to get additional assistance.
With regards,
