    Seems fairly clear, but in the help section of Microsoft 365 a lot of people are trying to configure SMTP for wordpress through several plug-ins. MS tech support folks are replying as if there is a solution.

    Instead are you saying that it is not possible to use a wordpress plug-in to set up SMTP so that emails can be sent from a 365 email account?

    I’d like to add for my comment above, this is for E1 and greater plans only (P1 plan does not allow it!!)
