Password reset email does not arrive

@BigWheel I have a working ticket from Plex support but they are telling me I have to contact microsoft. I have done everything I can in my MS Exchange tenant to whitelist plex emails (allow from 192.254.122.79, @plex.tv, @mail.plex.tv) but this blocking is happening upstream from my available settings.
I have asked for them to send the reset link in the support ticket but still have not received the response. What are the options here? I am a paying monthly customer for over 5 years. I opted out of the lifetime plex pass because I want to support Plex. My plex server has been down now going on day 3 due to no fault of my own which is unacceptable. I am sure I am echoing many others viewing this thread.
