Hi All ,
In my environment frequently i am getting account lockouts for the pop based email accounts (both internal and external user from internet).
So i just tried to find the caller computer name for the account lockouts.Finally i found that exchange CAS server is making those account lockouts.
I have enabled the protocol logging on the CAS server and i found the below mentioned error message.
"R=""-ERR Logon failure: unknown user name or bad password."";Msg=LogonFailed:LogonDenied"
Environment Details :
Exchange 2013 SP1
Client Windows Live mail.
Please all you tell me how to overcome this issue for my pop Email clients ?
Thanks & Regards S.Nithyanandham
