This morning I noticed that many, perhaps all, of the email addresses hosted by Outlook are only allowing us to send to one recipient at a time. This is causing our email queue to fill up.
At first I thought we were sending to too many recipients but several only had 3 or 4. What causes this? How do we get it fixed? (Deferred: 452 4.5.3 Too many recipients (AS780090) Thanks, Job
