I've configure Azure Ad connect to synchronyze my user account to my O365 tenant to use TEAMS only
All it's OK but after user migration I no longer receive emails, but you still can send them
When they send me a mail, I see it in log that Exchange 2013 route mail to our anti-spam server (use for external mail) then anti-spam route mail to exchange server which re route to anti-spam...
Why mail send by internal user who have synchronised are consider as external mail ?
