Some time ago to deal with a problem, that is, the user through the OWA page to change the password, prompt success, but the logon does not prompt the user name password is incorrect.
In this case, the first reaction to the password modification must be successful, but the hint indicates that there must be a front-end server problem, and at least IIS problems.
So at this point, need to do is not panic, but in turn, access to all the OWA page services in the front-end server Internal page address, with the password after the login, you will find that there is one or more of the user name password error, but some can log in, so you just need to restart the IIS service is good, This problem, in fact, is a more common problem.
