This one is configured to use Certificate - yes. We are in hybrid mode so the one receive connector I have is FROM "Your organization's email server" TO "Office 365".

I tried changing the password of my user (which were indicated as a solution in some threads), but no avail.: Why does this not work? I would have thought that the paramters given would indicate that it was not anonymous. I did get it to work using direct send (option 2), but then I could only send to internal email addresses.

They are not affiliated/federated/connected with us in any way. I try to use the "SMTP client submission" (option 1) in article. Option is to use our SMTP sever, which will be Exchange Online (Office 365). 3rd party vendor (app vendor) wants to send emails from their app
