As with previous CUs, CU3 follows the new servicing paradigm that was previously discussed on the blog. The CU3 package can be used to perform a new installation, or to upgrade an existing Exchange Server 2013 installation to CU3. You do not need to install Cumulative Update 1 or 2 for Exchange Server 2013 when you are installing CU3. Cumulative Updates are well, cumulative. What else can I say,,,,
After you install this cumulative update package, you cannot uninstall the cumulative update package to revert to an earlier version of Exchange 2013. If you uninstall this cumulative update package, Exchange 2013 is removed from the server.
Note that customised configuration files are overwritten on installation. Make sure you have any changes fully documented!
What do I mean by that? Well, you need to ensure that you are fully informed about the caveats with the CU and are aware of all of the changes that it will make within your environment. Additionally you will need to test the CU your lab which is representative of your production environment.

Is there a previous case or link for this?
This sounds very much like a use case for RMS, but need to more details to comment properly.
After upgrading to CU3 we are having trouble accessing EAC in our hybrid deployment. When we use the internal or external URL we are redirected to the OWA cloud location, and do not have a mechanism we can find to re-establish a session on the internal server EAC interface. Is this a known issue? Is there a work-around?
Is this only when you hit the on-prem EAC link Bill? What happens when you hit the on-prem /OWA site?
I am having the same issue as Bill. We applied cu3 in our 2010\2013 environment now we are unable to access the 2013 EAC with the https://servername/ecp/?exhclientver=15 link. I was able to create a 2013 admin user to connect to the 2013 ecp but this did momentarily cause issues with our 2010 owa and remote devices. Any idea if there will be a fix for this soon?
I don't see the names after the recent blog upgrade - you are listed as anonymous :(
What happened to break 2010 by creating a 2013 admin mailbox - can you expand on that please?
