I will check the replacement now and post update here. Also, can you send into my DM exactly which email are working and not(the two random mail you checked that worked)?
Update: checked 4 and stopped checking. first one in the throwbin works, the rest doesn't have inbox. I didn't say none of the account are accessible. I said the email:pass is valid just most of them doesn't even have an inbox with them.
How are you trying to log into the mailbox? Through microsoft? thunderbird?
