All other methods of Activesync and web access to my Exchange server are working fine with no errors or issues, but when we attempt to configure Android phones for the server, it will only work with 'verify certificate' checked off. Ideally, I'd like my users to be able to use the default configuration, which includes the 'Verify Certificate' option. My primary question is: 'What does Verify Certificate do?', as I imagine if I knew that, I might have some idea why it isn't working.
