Change the size of the message state database

The BlackBerry® Messaging Agent uses a message state database to manage the mapping between email messages
on BlackBerry devices and email messages on the Microsoft® Exchange Server. The size of the message state database
defines how many recent email messages are kept in this mapping for each user. Increasing the size of the message
state database might decrease the message load on the Microsoft Exchange Server because the BlackBerry Messaging
Agent can use the local message state database to search for messages instead of communicating with the Microsoft
Exchange Server. Increasing the size of the message state database also increases how much memory the BlackBerry
Messaging Agent uses.
If you change the size of the message state database, your organization's environment might experience a serious
performance impact.
1. In the BlackBerry Administration Service, on the Servers and components menu, expand BlackBerry Solution
topology > BlackBerry Domain > Component view > Email.
2. Click the instance that you want to change.
3. Click Edit instance.
4. On the Messaging tab, in the Performance section, in the Message state database size field, type a value
between 0 and 1000, that specifies the number of messages that the BlackBerry® Enterprise Server keeps in the
mapping for each user.
The default value is 100 messages.
5. Click Save all.

sends a request to the BlackBerry® Enterprise Server to convert the attachment. The BlackBerry Enterprise Server
uses a BlackBerry Attachment Connector to send the attachment data to a BlackBerry Attachment Service, which
