ActiveSync Device Status

Administrators must constantly track the devices connecting to ActiveSync, so that they can proactively identify devices that are unable to sync with user mailboxes, the users using these devices, and the probable reason for the non-sync, much before device users even notice that something is wrong! Likewise, administrators should also be able to zero-in on devices that are connected to ActiveSync, but have been inactive for long time periods, so that they can take efforts to clear out such devices en masse. To isolate such devices, administrators can use the ActiveSync Device Status test. This test reports the count of devices that are using ActiveSync without a glitch, those that are having problems using Activesync, and the stale (inactive) devices. Using the detailed diagnosis of this measure, the devices that are operating well, those that are not, and those that are stale can be clearly isolated.

Target of the test : An Exchange 2013/2016 Server

Agent deploying the test : An internal agent

Outputs of the test : One set of results for the Exchange server being monitored

Configurable parameters for the test
  1. Test period - Indicates how often this test needs to be executed.
  2. Host  - Indicates the IP address of the Exchange server.
  3. port – The port number of the Exchange server. By default, this is 443. 
  4. xchgextensionshellpath - The Exchange Management Shell is a command-line management interface, built on Windows PowerShell which enables you to administer every part of Microsoft Exchange. This test uses the Exchange management shell to run scripts and collect the desired performance metrics from the Exchange server. By default, the test auto-discovers the location of the Exchange management shell and thus, automatically loads the Exchange management shell snap -in (exshell.psc1) for script execution. This is why, the xchgextensionshellpath is set to none by default.
  5. inactive device age in days – Specify the minimum duration (in days) for which  a device should not have synchronized with its mailbox for it to be counted as a stale/inactive device.
  6. show dd for ok status device – By default, this flag is set to No, indicating that detailed metrics will not be available by default for the Device with OK status measure reported by this test. To ensure that this test collects detailed metrics for this measure, set this flag to Yes.
  7. DETAILED DIAGNOSIS – To make diagnosis more efficient and accurate, the eG Enterprise embeds an optional detailed diagnostic capability. With this capability, the eG agents can be configured to run detailed, more elaborate tests as and when specific problems are detected. To enable the detailed diagnosis capability of this test for a particular server, choose the On option. To disable the capability, click on the Off option.

    The option to selectively enable/disable the detailed diagnosis capability will be available only if the following conditions are fulfilled:

    • The eG manager license should allow the detailed diagnosis capability
    • Both the normal and abnormal frequencies configured for the detailed diagnosis measures should not be 0.
Measurements made by the test
MeasurementDescriptionMeasurement UnitInterpretation

Device with OK status:

Indicates the count of devices that are currently able to synchronize with their mailboxes via ActiveSync.


Detailed diagnostics will be available for this measure only if the show dd for ok status device flag is set to ‘Yes’.

If available, then, you can use the detailed diagnosis of this measure to know which devices are able to connect to ActiveSync and synchronize with their mailboxes, and which users are using these devices.

Device with not OK status:

Indicates the number of devices that are currently unable to synchronize with their Exchange mailboxes via ActiveSync.


Ideally, the value of this measure should be 0. A non-zero value for this measure implies that one/more devices are unable to synchronize with their Exchange mailboxes. To know these devices and their users, use the detailed diagnosis of this measure.

Stale devices:

Indicates the current number of stale devices.


Use the detailed diagnosis of this measure to know which devices are inactive, which users are using such devices, and how long these devices have remained inactive.
