  1. Hi, I'm struggling a little using OAUTH2 with Exchange POP3. I can get connected to the pop3 server ok. (+OK The Microsoft Exchange POP3 service is ready.) When I use pop3.Auth , I get a "-ERR Authentication failure: unknown user name or bad password" error. I have of course checked passwords and username many times. The same ones work fine with other mail apps. The problem I have is that I am not sure at which end the problem is. Exchange has POP3 and IMAP enabled for the use that I am using for testing etc. I am assuming that I am getting through the AAUTH hoops as the pop3 client seems to connect ok. Any pointers or help would be appreciated. Thanks AndyC++

    OAUTH and Exchange POP 3

    Thanks for that. I will go digging in Active directory, I probably missed an app permission somewhere. AndyC
