SDP Cloud No Longer Fetching Emails

SDP Cloud No Longer Fetching Emails

Last week we had issues with up to a 4 hour delay in fetching emails and generating tickets. Today SDP Cloud will no longer authenticate to Office365. It stopped fetching emails about an hour ago and when I change teh information in Mail Server Settings I receive the following error:
Failure:Email settings saved. But error occurred while trying to check connection with mail server - Authentication Failed:[AUTHENTICATE failed.]
