This is a cron job email that comes into a service account daily, the flows are not picking up the email and attachment any more , I have emptied the email box out and it still fails it is not a capacity issue , checked firewalls and permissions no changes , the mail box is not corrupted as it recieves many more cron job emails from other sources daily successfully just this flow will not trigger any more. no-one has touched the account to make it fail please help .
