expected XML node type was Element, but the actual type is EndElement

[Exchange Web Services] Sending email failed due to the following error: The expected XML node type was Element, but the actual type is EndElement.

Getting this error infrequently when trying to send an email with an exchange account. I am able to temporarily fix this by removing and re-adding the account to emclient, but it ends up happening again after some time. Once I get the error NOTHING will leave the outbox.

I can send email fine in the web client that is available so I know it’s not my email provider.

I am running emclient version 10.1.5131 (69d0414) on windows 10

Anyone have any suggestions?
