Hi Folks,

 

I have a thingworx 9.3 version running with basic auth (username/password) and want to implement some modern authentication for my SMTP/Mail notifications. Can anyone guide if its possible to have an advanced authentiction in place like 

-XOAUTH2 or OAuth 2.0 

-Exchange SMTP Relay

-Microsoft Graph

Hi @ TN_10343863

You’re running such an old release of the product that I doubt any of these technologies are supported.  I was able to dig up the 9.0 - 9.4 Help Center link for your review.

If you’re able to upgrade, we added OAuth 2.0 in the 10.0 release of the product.

Note:  The most current ThingWorx version is 10.1, but 10.2 will be released in a couple of months.

Regards.

You can use the SendGrid API directly without any direct SMTP connection if you want. 

That being said, the Mail Extensions supports OAUTH since ThingWorx V10.0 if you really want to send the emails via SMTP protocol.

looks like TWX 10 is a must for this to be done. Thanks for the response.
