2.1+ versions causing failures to send email

Hi

We have been using 0365 for a while, but since the system went from version 2.0.38 to 2.1+ none of the sends work anymore as we get Account not authenticated, when we roll back to 2.0.38 everything is fine. I saw a comment at v2.1...master which suggests all tokens need to be reproduced which we tried, but it still doesn't work. Note : we generate the tokens ourselves using a generic oauth program and we also use a custom store to retrieve secrets from an azure key vault.

Any help appreciated!

Hi, tokens have to be “msal formatted”.

Either you get them using msal or transform them with that format which is …difficult to say the most.

The problem is older token format doesn’t work anymore as auth is performed using msal and follows the msal token format.
It was impossible (and also not very good in terms of security, maintainability, etc.) to hold both token formats as valid.

Regarding the custom store, it should be easy to do inheriting from the base token backend.

I’m sorry for the inconvenience

Or you can just pin 2.0.38
