Inconsistencies with Email functionality (tool & events) after upgrading to 2020.3

[No_Sass]

We upgraded to 2020.3 from 2019.1 earlier this spring and have noticed inconsistencies w/ the email functionalities available since. We've been unable to pinpoint specific instances where emails will send and won't send.

- Generally, we'll see, that in the results log of scheduled workflows, it'll show "Event has been completed" when the intended recipients hadn't received the email.

- We'll also see instances where only some of the listed emails(either in 'TO', 'CC', 'BCC') will receive an email. 

- We received this from an IT investigation...

We looked over the SMTP logs. It appears that something happens on the Alteryx side as, if we see the name in the SMTP Log TO: field or CC: field, the user gets it but when it is delivered to our server, if name isn’t there they don’t get it.  We can’t explain why name did not show up in the field but that is what your(Alteryx) server is sending to us.

What's missing? Is there a configuration that needs to be completed in designer? Is there a configuration that needs to be completed on the server? The issues are occurring when workflows are executed both in designer and run on the server. Was there a functionality change w/ email between 2019.1 & 2020.3 where adjustments will need to be made? 

Any thoughts/guidance would be appreciated.

Hi @No_Sass,

Linking some similar posts here (Link 1, Link 2) for reference. Do either of these help address your issue? If not, can you confirm if there are any attachments being sent in the email or if you can see any patterns with the users who are not receiving the email?
