Is it possible to access and update Exchange accounts?

Question

In my project I need to access the Exchange accounts on the device, to change them.

I need to do it programatically , inside my application.

I have searched around but it does not seem that there is a way of doing such a thing.

Please any help or suggestion?

EDIT EDIT

To be more specific i need to: lists all email accounts on the device and allows the user to change settings for Exchange accounts:

*server address

*server port number

*SSL (on/off)

*accept all SSL certificates (on/off)

*account password

Answer 1

You can't modify the permissions/settings of an another exchange account (it gives you a security error). You only can create your own exchange account witch it will be included in your exchange accounts as yourAppName..

Answer 2

Take a look at AccountManager (http://developer.android.com/reference/android/accounts/AccountManager.html)

You should be able to do something like this:

AccountManager accountManager = AccountManager.get(context);
Account[] accountList = accountManager.getAccounts();
for(Account account : accountList){
    accountManager.getUserData(account, AccountManager.KEY_USERDATA);
    accountManager.setUserData(account, AccountManager.KEY_USERDATA, "data");
}
