New setup - unable to login Connect for Microsoft 365

[bdub_aegis]

Hello Jeff,

Thank you for your reply however, I'm not having an issue with 2FA on the O365 account - I know how this works. The issue specifically is with the Xerox app "Connect for Microsoft 365". When I attempt to sign in I'm essentially forced into a sign in loop. I reached out to Xerox support and was instructed to open a forum case here. If you can provide any information on troubleshooting the Xerox app "Connect for Microsoft 365", I would greatly appreciate it.

Also, I don't know what link you posted, but that has nothing to do with O365.

Best regards,

-Bdub

My name is Bradley. I've been working with a client who has a Xerox AltaLink C8155 that is serviced by a local printer reseller, and they're recently installed the "Connect for Microsoft 365" app on their MFP as we are trying to move away from traditional scan to SMB and looking to setting up scanning to Sharepoint. When I attempt to sign in with an account using the primary credentials, authenticating with 2FA, I'm asked if I want to stay signed in. Which ever option I choose, I'm then brought to a landing page, the screen greys out and I'm presented with an error message:

Application error received from service. Error code: 400.

I've ensured TLS 1.2 is in use in the printer security settings, but upon researching this I haven't been able to find any clear resolution to this issue. Any advice/guidance would be much appreciated!
