Hi All,
So I had asked about this back in 2022 (see below). If you search for OAUTH you will see it (in the forum). We are currently exploring options but I want to confirm with anyone. If Microsoft does go forward with this time line will *web\email basically stop working for anyone relaying emails thru Office 365?
Thanks,
Jerry
Microsoft has updated its timeline for retiring Basic Authentication (username/password) for SMTP AUTH in Exchange Online. While initial deadlines were earlier, the new schedule sees Basic Auth disabled by default for existing tenants at the end of December 2026. New tenants will have it disabled starting in 2027.
Hi Jerry,
Once basic authentication is turned off you will need to use OAuth2 to authenticate. You will get a error from the server otherwise.
PxPlus and *web/email support OAuth2 authentication as of PxPlus 2025 (v22).
Check out the doc here (https://manual.pvxplus.com/page/Web%20Utilities/Email%20Utility/Overview.htm) there are several examples at the bottom on how to do this.
Thank you Devon.
