For the past few weeks we have experienced e-mail problems with Hotmail domain senders.
Only the Hotmail accounts are not coming in, all other domains work just fine. We can also send anywhere as well.
I have not made any changes to our Exchange2013 server or spam services, everthing is working as it was before.
Please help, I have the SMTP logs and the emails generated from Hotmail addresses never even left the Microsoft servers.
Almost as if my domain is listed as internal for Microsoft.
Thank you!
