Hello,

 We have Service Desk plus installed locally, we also have a O365 hybrid environment. I have been trying all different combinations in the service desk email settings and I can't successfully connect an incoming connection. I have tried outlook.office365.com and the IP address of our hybrid server.

 I am able to sign into office online (portal.office.com) using the same email address and password.

I get these two errors depending on the configuration I try in the email settings.

Any idea's we could try to setup an email connection?

Errors..

Problem connecting to mailbox

Authentication Failed using the given username and password - The email address and password I'm using works fine online.

Thank you

Larry
