Hey, team - one of the IT people for one of my customers asked the following question:

I have a question about how acumatica sends emails. Does it fully authenticate the email address and send the email legitimately from the Microsoft 365 domain? 

 

I figure someone on the Community can point me to a detailed response fairly quickly.  Any insight, links, etc. would be helpful here.  Thanks!

@nickcerri32 First of all depends on the way email is being setup on acumatica and what authentication method being used. However, If we assume the modern Authentication and external application being used, there is a trust and shared token between Acumatica and Office 365 which allows to send/receive without authenticating every single time. That does not mean emails will not be available on exchange Server as at the end of the day, Acumatica act as a mailing agent, despite not same as outlook or other actual mailing agent, and any transaction will be through Office 365.

If there is any specific doubt or question, please mention or contact Acumatica Support for further details.
