Stopped receiving mail validation emails from microsoft - Microsoft Community


hi, 

i admin in 200-user firm. due business model purchase office h&b licences , tie these ms live accounts, email address being *** email address removed privacy *** . have stopped receiving mail validation emails. new account register, cannot verify. have checked gateway, nothing hitting us, smtp logs showing absolutely nothing. 

the emails coming *** email address removed privacy ***

to add, have several other domains configured same way, , after doing tests on these domains - emails coming through fine. looks if there kind of block on microsoft side; perhaps if sampledomain.co.uk detected - dont send email. @ possible ? if yes, how can unblocked ? 

i have raised ticket support, these guys trying me verified different way, while problem cannot 200 accounts...  please help, response welcome !

kind regards, 

luke
