Active Sync = Active Sync ?

Active Sync hat sich in den letzten Jahren als der Standard-Synchronisationsmechanismus von Exchange für mobile Endgeräte herauskristallisiert. Nahezu alle wichtigen mobilen Endgeräte unterstützen dieses Protokoll.

Jedoch unterstützen nicht alle Hersteller alle möglichen Features – Christian Schindler von NTX hat auf seinem (übrigens ganz ausgezeichneten) Blog  einen Technetartikel verlinkt, der eine gute Übersicht zeigt, welches Endgerät was kann. (Ich bin übrigens schon sehr gespannt, was davon Windows Phone 7 unterstützen wird.... )

Notes:
1 Requires free Outlook Mobile update
2 Only finds email address, no additional info
3 3rd party downloadable client available for purchase for RIM BlackBerry devices
4 Because this is an application, a remote wipe wipes all data in the application but not the entire device
5 S/MIME performance depends on how S/MIME is used[7]
6 Encryption is for the applications memory and not the entire device
7 Policy is available but is client-side only and thus does not respond to server-side policy settings
8 Phone number and email address only
9 can only create personal calendar entry, no meeting requests
10 Info is derived from other info sent from the device as opposed to sent in the protocol
11 E series devices do a full wipe while N series devices only do a wipe of the Exchange data
12 Some devices have a conversation view which is simply grouped by subject and is not the EAS based conversation view feature
13 S/MIME was not included in EAS 12.0 so it was added back at this point (it had been in EAS 2.5)
14 Information in this chart is additive. This means that information that is listed for a later version of Exchange ActiveSync does not list the features of the previous version but the product does include them. Compatibility in an earlier version indicates compatibility in the later version unless otherwise noted.

Viel Spaß damit
