I'm on a Samsung Galaxy Nexus with Android 4.0.2.
If I go to Settings, Accounts & sync, ADD ACCOUNT, there is no "Corporate" or "Exchange" options at all. I only have Facebook, Google, Twitter, and Dropbox. I haven't rooted my phone or made any modifications beyond installing apps from the Play store.
Under Settings, Apps, ALL, I have something listed called "Exchange Services" but it says that it is using 0.00B storage, cache, etc.
Any help on adding an exchange account to my phone would be appreciated. I've been using it with just my Google account for quite a while but would like to add a corporate exchange account for work.
