At the moment the Android operating system was launched on the market, many users have complained about the incapability to connect with the Exchange servers, for loading contacts on their devices. This lack of Microsoft Exchange support was easily remediated using an application created by a third party developer. The first application created with the role of enabling users to synchronize their Android devices with the Exchange servers, was created by Intermedia and Wrike. This application was launched under the name of ContactSync, and offered the possibility to Android users to load the contacts on their mobiles.
Even if this app has not offered all the features of a full Exchange synchronizing, it was still considered a welcomed solutions. This app came at that moment with the following features: the possibility to loan contacts in the phone, to plan a full calendar synchronization, and to change or configure the address of the Exchange Web Services.
In time, the Google Android exchange support has developed a lot, in order to allow Microsoft Exchange administrators to implement this feature on the Android devices. For example, for devices having the Android 2.2. and 2.3 versions, the exchange support is available if these are running on Microsoft Exchange ActiveSync 2003 Service Pack 2, Microsoft Exchange ActiveSync 2007 or 2010. With this feature available, users can synchronize their Contacts, the Calendar, Email, Settings, and all applications related to these.
In order to use the Microsoft Exchange Information Services, users have to comply with the applicable security policies. When establishing a mailbox policy for an ActiveSync server, users can also remotely wipe the content on any mobile that used an account from this server. This remote wipe will act as a reset of the factory data, and will erase all the personal data that was stored in the mobile, including here Google accounts, Exchange accounts, and other accounts. It will also remove the apps downloaded and the application settings. If files were stored on the Android device SD card, these will not be erased when the remote wipe will be performed. For setting up the ActiveSync mailbox policy, the phones have to be secured with a PIN code, having a minimum number of letters or numbers.
On an Android device, users can add sync information and accounts from various Exchange servers, and at the same time they can add multiple Google Accounts. As each of these accounts can have various security policies, in some situations these can enter in confliction. In this situation, Google Android is enforcing the rules that are strictly settled up by each account for each type of policy. Therefore, there is no account policy that can reduce the security degree settled up by another account policy.
