Duane,
Queued mail for delivery
Those errors ...
As mentioned to Drew and Frances, those responses are not errors.
It shouldn't keep the emails from eventually being delivered,
In fact, it is almost a statement that the message will be delivered (diversion to Spam or another folder is also considered delivery).
though no one can be sure how long the delay is,
Microseconds to minutes is the range you should expect. Programmers often use queues to organize things; it doesn't necessarily imply a perceptible delay from a human's point of view.
and there's nothing GIO can do about it.
Not about those particular response codes, but there could be other issues going on with delivery to Microsoft-powered services. That's happened in the past and could require GIO's intervention to straighten out.
