If the android is running the 2.2 Froyo update, the exchange native client won't work, download the trial of the "touchdown" app and see if that connects fine.
How are you connecting the Blackberry, they only work with exchange push..., AFAIK there isn't a local pull / Activesync client Cheers!

A couple of types of phones are blackberry's (not using the BES server for these connections) that uses the OWA feature to connect and also one phone running the Android OS. Both of these users can log into their OWA account just fine from a web browser, but they get authentication failures when trying to put in the domain\username and password credentials from their phones to try and sync e-mail. We are following the instructions to type in all of the necessary info for the OWA on Exchange 2010. Has anyone run into this issue before with Exchange 2010?
