제목: [mailop] Anyone noticing a backup of Microsoft hosted emails...
_______________________________________________It’s seems like it’s an intermittent issue here, but I’ve been getting quite a few temporary errors sending to MS hosted accounts.
Error: 451 4.4.3 Temporary server error. Please try again later ATTR2
Eventually they go out, and it doesn’t seem like we hit any thresholds that I can tell.
Sincerely,
