Dear Experts,

We are in the middle of testing a migration of an SBS 2011 (running Exchange 2010 SP1) over to Server 2012 R2 with Exchange 2013 installed. The new 2012 R2 has all FSMO roles.

After the successful Installation of Exchange 2013, we are unable to logon to the Exchange Admin Center (https://localhost/ecp). Says bad username or password. My admin is a member of the Organization Management Exchange Security Group, along with "Organisation-Admins" and "Schema-Admins" .

Any ideas? Thanks, Oliver

Hello

check security log for Audit Failure and share error message: like:

We are not getting any errors in our Security Log. However, our Application Log generates the following errors every minute:

... and the following Warning:

Does that help?
