Our email stopped working and this is the error on the message. Anyone else notice this?

Is this Office365 or Acumatica ?

Hello, Did you see the related knowledgebase article in this forum?  I searched your error and found lengthy instructions.  This will be relevant if you’ve had recent changes to your email configurations in Acumatica.

Of course, the million-dollar question is ‘What changed since email last worked?”


Good luck.
