Hi all... I'm aware of the recent changes to Exchange disabling Basic Auth. Does this basically mean that cfexchangeconnection is dead and everyone will need to implement some integration with the Graph API?

No, it means do not use unencrypted communications for Exchange moving forward. If you have an exchange box on-prem vs Office 365, the tag will still function as is, without any kind of modification.

I think CFexchange is dead until this is fixed. https://tracker.adobe.com/#/view/CF-4212511

Correct, I found that thread yesterday. And too @Evil Ware’s point, techincally, the cfexchange tags are still useful if you use a on premise Exchange server, but if you are using cloud-based Exchange through MS, Intermedia, etc... you are facing a severe outage and forced to integrate with MS Graph API to connect to your exchange server now. Adobe drops the ball again.

Not the MS graph API, you need to use the MS Exchange online from AzureAD, in order to work with your settings you need API token to configure.

Maybe there are multiple api options... we are already up and running on one project using Graph API in order to open emails and extract attachments from them.
