EAS14/14.1 protocol beta
In order to enable version 14 and 14.1 of the Exchange ActiveSync protocol for an account, simply check the "Use EAS14Beta" checkbox in the ZxMobile tab of an user's settings.
ZeXtras Mobile and Samsung devices
Due to the amount of manufacturer customizations causing issues and out-of-spec behaviours of Samsung clients running the stock client on Android, ZeXtras Mobile includes some specific server-side limitations to avoid as many synchronization issues as possible.
Since the vast majority of issues has been detecting when using versions of the Exchange ActiveSync protocol higher than the old 2.5, a dedicated module property, "ZxMobile_MaxSamsungVersion", has been introduced to define the maximum protocol version usable by Samsung clients. This property is set to default to "2.5" and cannot be overridden by either EAS Filters or by the various "ZxMobile_EASXX" properties, meaning that this value is the ONLY reference for all Samsung clients.
Using version 2.5 of the Exchange ActiveSync protocol will make devices unable to benefit of the following features:
Server-side mail search.
Email flagging.
Mobile Provisioning.
It's always possible to change the value of the "ZxMobile_MaxSamsungVersion" property either via CLI or via the ZeXtras Administration Zimlet to use a higher protocol version, but doing so will likely cause one or more of the following issues:
Inability to download full emails if the default download size is set to a value lower than the email's size.
Duplicated device notifications.
Inability to properly accept or sync Meeting Requests.
Synchronization loops.
We are eagerly working on fixing as many issues as possible due to server-side workarounds, but at the moment setting the Max Samsung Version limit to 2.5 is highly suggested.
