Office 365 : enable basic auth temporarily ?

Eric 25 Reputation points

Hi everyone,

Since January 1st, Microsoft has completely removed the basic auth from its Office 365 Exchange. Only I'm stuck in a mail migration because for the moment I have no other choice than to use this basic auth.

Is there a way to temporarily re-enable it for only one user? Either via the Office 365 interface or in Powershell? Or another alternative ?

On a similar topic, one eprsone indicates that she was able to do this but I don't understand the steps she describes (API ? ) :

Thanks, Eric

    Hi @Eric ,

    Agree with Vasil Michev said, Basic authentication is permanently disabled on October 1, 2022. Now that the date has passed, you (or support) can't re-enable Basic authentication in your tenant.

    Nope, that ship has sailed. You can always open a support case to confirm, but prepare to be disappointed.
