Does anyone have the same occurrence where Marketing Cloud is not delivering emails to microsoft domains i.e @live, @hotmail, @outlook?
If so is there a particular issue and can it be solved?
I can confirm that i have sent emails in various manners, template testers, developer testing campaign sends, subscriber opt in / welcome emails and they do not get through.
Other domains are fine as per the send report below.
We have used Marketing Cloud for close to 2-3 months and have warmed up our IP properly.
