![]() ![]() EAS 12.0 was a complete re-write of the protocol (in managed code) from its previous version. Tasks syncing was added as was S/MIME email encryption and the following policies were added:ĮAS 12.0 came with Exchange Server 2007. The ability to remotely wipe a device was also added so administrators could remove company data from a device that was lost, stolen, or after an employee left the company. Global Address List (GAL) search was added to enable people to look up other co-workers in their company directory to find their email address. This version also introduced Direct Push, a real-time push e-mail solution which allows the server to say "I have a new item for you" and then tells the client device to do a sync. The EAS protocol also moved from a Globally Unique Identifier ( GUID) to 1:X short IDs for all items which reduced the amount of data sent across the wireless network.ĮAS 2.5 (Part of Exchange Server 2003 SP2) was the first version of EAS to be written by the Exchange Server team. Ghosting tells server what they can sync and then all is sent down but when changes are sent up, only specified fields are changed (others are not deleted). In Exchange Server 2003 SP1 ghosting support was added to EAS 2.1. Because of the use of SMS as a notification, the configuration of an SMS gateway was required and each account needed to be configured with a user's mobile phone number. ![]() Always Up To Date (AUTD) was implemented as a way to let a device know if there was new information for it and Short Message Service ( SMS) was the technology used to deliver this information to the device. EAS used WebDAV to connect to a user's mailbox and added the ability to sync non-default calendar and contacts folders. This version of the protocol was developed by the Microsoft Windows Mobile team and was delivered as a binary drop (massync.dll) to the Exchange Server team. This initial version of EAS has the user’s device “pull” data down rather than have the server “push” new information as soon as it was available.ĮAS 2.0 shipped in Exchange Server 2003. This version of EAS communicated over Web-based Distributed Authoring and Versioning ( WebDAV) to Exchange 2000 servers syncing Email, contacts, and calendar and allowed users to select a folder list to sync but this was only for email folders (not contacts or calendars). The first version of EAS (called AirSync at the time) was a part of Mobile Information Server (MIS) 2002. Īpart from the above, EAS client support is not included on: The built-in email application for Windows 8 desktop, Mail app, also supports the protocol.
