Exchange Online mailboxes cannot be managed by using EAC after you deploy Exchange Server 2013 CU6
After you deploy Cumulative Update 6 (CU6) for Microsoft Exchange Server 2013, you cannot manage Exchange Online mailboxes by using Exchange Admin Center (EAC) from an on-premises server. This is because some tasks are unavailable. For example, you can no longer do the following in Exchange Online:
- Create a mailbox
- Change a mailbox
- Create or enable an archive mailbox
The problem occurs because of a missing configuration option in an EAC settings file.
To resolve this issue, install Cumulative Update 7 for Exchange Server 2013.
To work around this problem, Microsoft has provided a supported script. Administrators can apply this script to affected systems to restore the missing EAC functionality.

On the affected server that is running Exchange Server 2013, this script changes the EAC configuration option and restarts Internet Information Services (IIS). During the IIS restart process, users who are connected to the server that is being updated are disconnected briefly.
