# AirSync Module Configuring the AirSync Module Managing AirSync Devices Compatibility Notes The CommuniGate Pro Server can be used with Microsoft® Windows Mobile and other compatible devices (PDAs, smartphones) supporting the AirSync protocol - a client-server version of the Microsoft ActiveSync protocol. The AirSync protocol allows a client device to synchronize its Calendaring, Tasks, and Contacts data with the same data in the user Account on the server. The protocol also allows a user to synchronize some or all of its E-mail mailboxes, to compose and send E-mails, Event invitations, and Event replies. The CommuniGate Pro Mailbox Alias feature allows AirSync clients to access shared Mailboxes in other Accounts. The AirSync protocol allows a client device to access the Server Directory.

## Configuring the AirSync Module

The AirSync protocol works over the HTTP protocol, so the AirSync module does not have its own settings. Since the Windows Mobile clients are designed to access only the standard HTTP ports (port 80 for clear-text connections and port 443 for secure connections), make sure your HTTP User module is properly configured to accept connections on these ports.

## Managing AirSync Devices

Server and Domain administrators can monitor and manage AirSync devices employed by the Account user.

Open the Account Settings WebAdmin Interface page and follow the Mobile link. Find the AirSync Devices panel:

AirSync Clients
| Client Type | ID | Policy | Last Access | Remote Device Wipe
--- | --- | --- | --- | --- | ---
| PocketPC | 9999BFE4D66C4BE29AAB1DF8F8CF4064 | {UsePIN=YES;} | 10:54:48PM | 1-Oct-08
| PocketPC | FAFABFE4D3333BE2ABBC2E0909D05175 | {} | 20-Sep | pending

The table elements show the device type and unique ID for each device the Account user has used, as well as the time of the last AirSync operation with that device.

Devices can be protected with a PIN (password) that needs to be entered every time the device is switched on, or after a period of inactivity. You can remotely enable or disable this function: select the device element and click the Enable PIN-lock or Disable PIN-lock button.

To remove all information from the device (if it has been lost or stolen), select the device element and click the Wipe Out button.
The device element will display the `pending` marker.
Next time the device tries to connect to the Server, it will receive a command instructing it to remove all E-mail and other data stored locally on the device.

To cancel the Wipe Out operation (if the device has been recovered before it tried to access the Server), select the device element and click the Cancel button.

You may want to restrict AirSync access to an Account to certain devices only:

Enabled Mobile Device IDs

If this list contains the `*` element, then all devices can connect to this Account. Otherwise only the devices with device IDs included into this list can connect to this Account.

Some devices may fail to deal with all user Mailboxes - either because the user Account has too many Mailboxes, or because some Mailbox has too many items in it. A user can "hide" certain Mailboxes from the AirSync client by disabling the Visible to Mobile Devices Mailbox option.

## Compatibility Notes

The AirSync protocol was designed to work in a proprietary, non-standard environment. CommuniGate Pro AirSync module makes its best effort to convert AirSync data to the standard formats (such as iCalendar and vCard).

### Replying to Event Requests

When an AirSync client accepts or declines an Event, it generates an E-mail message to be sent to the Event organizer. This message contains Microsoft proprietary data not suitable for any standard-based application.
To provide a workaround for this problem, the CommuniGate Pro AirSync module generates a Reply itself, using the standard iCalendar format. As a result, the organizer may receive 2 Event Reply messages - one from the AirSync module, and one from the Windows Mobile client itself.
Note: when the Windows Mobile user chooses to accept or decline a request without sending a reply, only the Windows Mobile own request is affected. The AirSync module generates its reply independently, based only on the Event request "RSVP" attribute.

### Sub-Mailboxes

AirSync clients do not support sub-mailboxes of the Sent and Trash Mailboxes, and older clients do not support sub-mailboxes of the INBOX Mailbox either.
If an Account contains such sub-mailboxes, the Server does not inform an AirSync client about them.
