Hi, Microsoft's SNDS system has no data for our IP addresses for the last 3 days, however one of our IP addresses appears to be getting rate limited:
451 4.7.500 Server busy. Please try again later from [XX.XXX.X.XX]. (AS77713180) [XXXXXXXXXXX.eop-XX01.prod.protection.outlook.com]: retry timeout exceeded I have already contacted their horrible level 1 support team by filling out the usual support form (and am currently waiting for their pathetic copy / paste responses that we always get), but I'm hoping someone on-list from Microsoft can contact me directly to provide some assistance. A lot of our customers are currently unable to email anyone on Hotmail, and all we can really tell them is "Hotmail's reporting system isn't working, and they're rate limiting our IP address for seemingly no reason", and recommending they move *away* from Hotmail. Any help would be great. Thanks.
