After testing the new server, I moved my mailbox over, and everything good, however my phone refused to connect using ActiveSync.
After much swearing, and a very useful visit to https://www.testexchangeconnectivity.com, I found out that Domain Admin accounts have Security Permissions inheritance blocked. This meant that the Exchange Servers group did not have the correct permissions on my mailbox.
To check whether inheritance is disabled on the user:
- Open Active Directory Users and Computers.
- On the menu at the top of the console, click View > Advanced Features.
- Locate and right-click the mailbox account in the console, and then click Properties.
- Click the Security tab.
- Click Advanced.
- Make sure that the check box for "Include inheritable permissions from this object's parent" is selected.
A few minutes later I was able to successfully sync my Android phone to my Exchange 2010 server.
