我正在尝试构建一个 ActiveSync 客户端应用程序。我有一个测试 Hotmail 帐户，其中包含过去 6 个月的邮件，其中大部分未读。Hotmail 使用 ActiveSync v2.5。我尝试了同步命令，但我只能收到新邮件，旧（> 3 个月）邮件不会出现！

我错过了什么还是它是这样工作的？

初始请求：

<?xml version="1.0" ?>
<Sync xmlns="AirSync:">
    <Collections>
        <Collection>
            <Class>Email</Class>
            <SyncKey>0</SyncKey>
            <CollectionId>00000000-0000-0000-0000-000000000001</CollectionId>
            <WindowSize>512</WindowSize>
        </Collection>
    </Collections>
</Sync>

回复：

            </Commands>
        </Collection>
    </Collections>
</Sync>

此外，相同的代码适用于 GMail 帐户（使用 ActiveSync v12.0）

Apparently, the Hotmail servers respond differently to different devices. I modified the User-Agent value sent to the server to Apple-iPhone/705.18 and it started working!

确保您没有传递FilterType会限制返回对象范围的元素。

Secondly, watch for a MoreAvailable element in the Sync response which would indicate that you haven't yet received all the objects from the server.
