Access to Exchange Admin Centre blocked using most (but not all) URL links
All those work fine for me, though we've often seen issues affect only a subset of tenants. That said, Microsoft is in the process of switching to the cloud.microsoft domain for the EAC as detailed in this message center post: Message center - Microsoft 365 admin center
As noted in the post, the old URLs will continue working for a while, as Microsoft has not announced any deprecation date yet. That said, if you are seeing issues with those URLs and you can reliably reproduce them, bet open a support case and report it.
Make sure you do your due diligence first though: test with another admin account; test from another browser, preferably via private session; test from another network location if possible; etc.
I have the same problem but none of the links work.
This is costing hours of my time.
It briefly worked after a colleague removed Exchange Administrator role and put it back but problem came back within ten minutes.
