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.
If this is set earlier devices report back that they do not support device encryption and 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 TouchDown honors SD card encryption by encrypting the attachments downloaded to the SD card using 3DES encryption.
19 Some Android models support this feature others do not and will report that they cannot connect due to not meeting the security requierments. The following support the feature: Droid Pro; The following do not support the feature: HTC G2.
Exchange ActiveSync Overview
Exchange ActiveSync Considerations When Using Windows Phone 7 Clients
The last 10 policies are in the wrong place on the table. They are a mix of 2003 SP2 and 2007 policies.
Could someone possibly update this table with WP 7.1 / Mango details?
this article states encryption is supported on windows 7 with exchange 2007 . while another ms site has NO
Totalnet32: Encryption was/is supported with Windows Mobile against Exchange 2007. Encryption is not supported with Windows Phone 7 no matter the Exchange Server version hosting the mailbox.
Matt: On my to do list and will do after I return from my Holiday :)
This is pretty out of date now, could someone please update with the new Android update.
ICEMAN_halo96: Please feel free to send me the updates (use: ExTW@microsoft.com) that should be included for Android, then I can incorporate them.
When will this be updated for WP 7.1? Will it show the new issues it has with EAS 2003 SP2? Mango broke some things that NoDo had working with EAS2003SP2
LiFePo4: Could you provide some info about what you saw broke with Mango?
When replying to an email the original email text is not included. This has been observed by several people and reported in multiple sites recently.
