Description

You can configure the BlackBerry Enterprise Server to send notification messages to users'

BlackBerry devices when the BlackBerry Messaging Agent cannot retrieve email messages from the

messaging server. The notification messages instruct users to check the email applications on their

computers for the email messages. By default this feature is turned off and notification messages are

not sent to the users' BlackBerry device.

1. In HKEY_LOCAL_MACHINE\SOFTWARE\Research In Motion\BlackBerry Enterprise

Server\GroupWise, create a DWORD value that is named SendByPassedMessageNotifications.

2. Double-click the new DWORD value.

3. In the Value data field, type 1.

To turn off this feature, set the value of SendByPassedMessageNotifications to 0.

By default, the BlackBerry Messaging Agent tries to retrieve a message from the messaging server

up to 5 times. If you want to change the number of times that the BlackBerry Messaging Agent tries

to retrieve a message, perform the following task:

1. In HKEY_LOCAL_MACHINE\SOFTWARE\Research In Motion\BlackBerry Enterprise

Server\GroupWise, create a DWORD value that is named MaxFailedMessageRetry.

2. Double-click the new DWORD value.

3. In the Value data field, type the number of times that you want the BlackBerry Messaging Agent

to try to retrieve a message from the messaging server before the BlackBerry Enterprise Server

sends a notification to the user's BlackBerry device. The BlackBerry Enterprise Server will only

send a notification if the feature is turned on. By default, users' will not get a message indicating

that a failure has occurred on their device.

Note: If you increase the MaxFailedMessageRetry value, the BlackBerry Messaging Agent tries to

retrieve messages that it previously failed to retrieve until the new threshold is reached for all failed

messages.

In previous versions of the BlackBerry Enterprise Server, if the BlackBerry Messaging Agent was

restarted while users' mail accounts and calendars were being reconciled between their email

applications and their BlackBerry devices, the reconciliation started again for each user.

In BlackBerry Enterprise Server version 4.1 SP6, if the BlackBerry Messaging Agent is restarted while

users' mail accounts and calendars are being reconciled between their email applications and their

BlackBerry devices and occurs within one hour of the shutdown, the reconciliation will start again for

each user. If the BlackBerry Messaging Agent is not restarted within one hour of the shutdown,

reconciliation for each user does not start again until the appointed time, if that time is at least 12

hours from the initial reconciliation start.

You can configure how many days to keep messages that are stored in the MbMailSync table in the

BlackBerry Configuration Database. By default, messages are stored in the MbMailSync table in the

BlackBerry Configuration Database for 90 days.

1. In HKEY_LOCAL_MACHINE\SOFTWARE\Research In Motion\BlackBerry Enterprise

Server\Database, create a DWORD value that is named MbMailSyncPrune.

2. Double-click the new DWORD value.

3. In the Value data field, type the number of days to keep messages in the MbMailSync table. Any

messages older than this number of days are deleted from the MbMailSync table.

If you set the value to 7 or less, this feature is turned off.

You can specify a delay (in hours) when using the Erase Data And Disable Handheld IT

administration command over the wireless network. This change applies to BlackBerry Device

Software version 4.5 or later.

The remote password reset cryptographic protocol is designed to allow you to set the BlackBerry

device password remotely, even if content protection is enabled on the BlackBerry device. This

change applies to BlackBerry Device Software version 4.3 or later.

You can use the Weak Digest Algorithms IT policy rule to specify algorithms that BlackBerry devices

consider weak. This IT policy rule can be applied to BlackBerry devices running BlackBerry Device

Software version 4.3 or later.

The BlackBerry Enterprise Server uses the list of weak digest algorithms when verifying that the

certificate chains for the certificates that BlackBerry devices use with the SSL protocol over

connections to external web servers are strong enough.

BlackBerry devices use the list of weak digest algorithms when verifying that the digital signatures

on messages that BlackBerry devices receive are not generated using a weak hash digest. BlackBerry

devices use the list of weak digest algorithms when verifying that the certificate chains for the

certificates used to sign messages that BlackBerry devices receive do not contain hashes generated

using a weak digest.
