I'm back again The_Exchange_Team navgupta , with something additional to gripe about in regard to the new admin center.... It is that I don't like how in the migration batch wizard, when onboarding to EXO, the target delivery domain is a dropdown menu which allows the other domains to be picked. I'm scratching my head why that is, as I feel it is only necessary to ever pick a different domain from the <tenant>.mail.onmicrosoft.com, when offboarding.
I just worked with a customer who were having autodiscover problems for their newly migrated users. Turns out, they were selecting one of their own domains for Target Delivery domain, and this was making their migrated users' Remote Routing Address be their original PSMTP. Of course, when attempting autodiscover, these users' Outlook clients were being redirected to try autodiscover again, using their PSMTP, and it would fail out, after wasting time exhausting all of the autodiscover methods.
In the old admin center, you couldn't / can't change the target delivery domain when onboarding. I believe this is an oversight in the new admin center, but please correct me if there is some use case that I'm missing (e..g like maybe you can now have multiple <tenant***>.mail.onmicrosoft.com domains in your tenant?).
