Over the last few weeks, I have been getting messages from *** Email address is removed for privacy *** that "delivery of message to *** Email address is removed for privacy *** has been delayed." Eventually, I receive another email about 12 hours later stating "Unable to deliver message to the following recipients, due to being unable to connect successfully to the destination mail server."
I can send to the same recipients from my Gmail account with no issues and I send another email to the same recipient again from my Outlook.com account and it gets delivered.
Any ideas on why the sporadic message delivery issues?
Thanks,
Keith
