Two days? I have been trying for 2 fucking years! I initially registered with <foo>corp.com domain email because that's what I use for Office 365 email account. They denied saying my domain doesn't match. So I tried to change the domain to <foo>.com and it appears to do it, but they keep saying they are still seeing the original domain. The entire Partner Network site is incredibly buggy, half of the site errors out. Their support is a total waste of time, they keep copy/pasting the same message over and over.
Sounds similar to my problem. At some point my Microsoft account was linked with an old startup email as a backup. I've updated it to fully remove it and set my gmail as primary. Yet I am still receiving subscription/billing emails to that old address, which fortunately is being forwarded. The UI simply does not reflect reality.
When I contact Support I tell them the whole problem at the start. Then eventually an agent comes on and asks me a dumb question. If I don't respond quickly enough they close the chat and the whole process restarts.
