Currently have installed teh wsgetmail, and setup the O365 side. Im able to connect to O365 but have been stuck with the following error message that I have not been able to resolve. I recieve this only if the mailbox has new emails. Normally if the mailbox is empty then it runs and gives me the processed 0 message.
/usr/local/bin$ wsgetmail --config=wsgetmail.json
fetching mail using configuration wsgetmail.json
