The following table lists the status codes for the Ping command (section 2.2.2.11). For information<br />
about the scope of the status value and for status values common to all <strong>ActiveSync</strong> commands, see<br />
section 2.2.4.<br />
Value Meaning Cause Scope Resolution<br />
1 The heartbeat interval<br />
expired before any<br />
changes occurred in<br />
the folders being<br />
monitored.<br />
Global<br />
Reissue the Ping<br />
command request.<br />
2 Changes occurred in at<br />
least one of the<br />
monitored folders. The<br />
response specifies the<br />
changed folders.<br />
Global<br />
Issue a Sync command<br />
request (section<br />
2.2.2.19.1) for each<br />
folder that was specified<br />
in the Ping command<br />
response to retrieve the<br />
server changes. Reissue<br />
the Ping command<br />
when the Sync<br />
command completes to<br />
stay up to date.<br />
3 The Ping command<br />
request omitted<br />
required parameters.<br />
The Ping command request did<br />
not specify all the necessary<br />
parameters. The client MUST<br />
issue a Ping request that<br />
includes both the heartbeat<br />
interval and the folder list at<br />
least once. The server saves<br />
the heartbeat interval value<br />
(section 2.2.3.75.1), so only<br />
the folder list is required on<br />
subsequent requests.<br />
Global<br />
Reissue the Ping<br />
command request with<br />
the entire XML body.<br />
4 Syntax error in Ping<br />
command request.<br />
Frequently caused by poorly<br />
formatted WBXML.<br />
Global<br />
Double-check the<br />
request for accuracy.<br />
5 The specified heartbeat<br />
interval is outside the<br />
allowed range. For<br />
intervals that were too<br />
short, the response<br />
contains the shortest<br />
allowed interval. For<br />
intervals that were too<br />
long, the response<br />
contains the longest<br />
allowed interval.<br />
The client sent a Ping<br />
command request with a<br />
heartbeat interval that was<br />
either too long or too short.<br />
Global<br />
Reissue the Ping<br />
command by using a<br />
heartbeat interval inside<br />
the allowed range.<br />
Setting the interval to<br />
the value returned in the<br />
Ping response will most<br />
closely accommodate<br />
the original value<br />
specified.<br />
6 The Ping command<br />
request specified more<br />
than the allowed<br />
number of folders to<br />
monitor. The response<br />
indicates the allowed<br />
number in the<br />
MaxFolders element<br />
(section 2.2.3.86).<br />
The client sent a Ping<br />
command request that specified<br />
more folders than the server is<br />
configured to monitor.<br />
Global<br />
Direct the user to select<br />
fewer folders to monitor.<br />
Resend the Ping<br />
command request with<br />
the new, shorter list.<br />
