Comparison of Exchange ActiveSync Clients

Notes:
¹ Requires free Outlook Mobile update
² Only finds email address, phone numbers, title and company
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
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.
¹⁵ Follow-up flags are implemented as "stars" on the device.
¹⁶ Device encryption is only supported on iPhone 3GS hardware and later. These devices are encrypted by default, therefore this setting is only used to check the devices status if the 'Allow non-Provisional Devices' policy is set (and the box unchecked). Once this is configured, earlier devices report back that they do not support device encryption and therefore access to Exchange will be blocked.
¹⁷ N900 is a non-provisionable device and does not support any policies. However, attachment downloading is always possible.
¹⁸ Device says it respects this policy but no device changes are made.
¹⁹ Supports gzip compression.
