I have installed Exchange 2013 CU6 to be part of a hybrid in-house/Office365 email domain for a small non profit agency. Exchange seems to have installed correctly. However, I cannot log in to the Exchange Admin Center (or OWA, or ECP). The login screen accepts the user name and password, blinks, and asks for the password again as if nothing happened. If I put in a bad password or user names, it give me a username/password failed error. Therefore, I know it is recognizing the correct password.

I have tried IE on the Exchange server and other domain computers, and all act the same way. I have created another account and Exchange enabled it, and it acts the same way all around. I cannot find any error messages on the Exchange server. The domain and forest are at 2008 R2 levels, and all domain controllers are 2008 R2. The Exchange server is on 2012 (not R2).

I have done some searching and not found anyone else describing a similar problem.

Any suggestions?

Hi,

From your description, I recommend you use the following URL to access EAC and OWA to check the result.

https://%computername%/ecp?ExchClientVer=15

https://%computername%/OWA?ExchClientVer=15

Hope this can be helpful to you.

Thank you, but those URLs did not help. The login screen still repeatedly pops up.
