The most bizarre thing is that I have another phone Samsung Galaxy A8 with Android 9 and MS Exchange ActiveSync account is working on that phone perfectly. Syncing addresses, contacts and calendar with PC-s and Office servers.
Account details are:
E-mail address: ***@outlook.com
Password: my microsoft account password (no app password)
Domain\username: ******@outlook.com
Exchange server: eas.outlook.com
Port: 445
SSL/TLS (accept all sertificates)
But as soon as I try to create the account on other phones (Blackberry Key2 Android 8.1 and Sony I V Android 14), I am getting error "Can't connect to server" or "Check your account settings and try again or switch to modernauthentication".
When I switch that modernauthentication on I am getting error "Can't connect to server".
When I try to create the account manually, I am getting message at the end of process: "Your account (xxx) can't be authenticated. Update your account settings and try again."
I tried both normal account password and microsoft app password.
I tried servers eas.outlook.com, outlook.office365.com, m.outlook.com
I tried domain/password with and without pre ""
I tried port numbers 443 and 993
