outlook exchange returns error on startup

Upon starting Thunderbird today, it appears the connection to my two Outlook exchange accounts (through an Owl extension) are no longer functional. I can receive messages but I cannot send them. I have attached images of the error it returns first (Error1) and then the screen that results upon refresh (Error2). I can reach and send mail from my accounts using Outlook365 web access, so it must be a Thunderbird configuration problem. Please help!

You will have to address your issue with the OWL developers.

Or move to the new native exchange support, noting it's limitations https://support.mozilla.org/en-US/kb/thunderbird-and-exchange

Thank you! I determined the problem appeared to be caused by not allowing cookies, but it is good to know that native exchange support is being developed!
