- You install Update Rollup 4 for Microsoft Exchange Server 2010 SP2 in an environment that is running against a Blackberry Enterprise Server (BES).
- The BES uses MAPI or Collaborative Data Objects (CDO) instead of Exchange Web Services (EWS) to communicate with Exchange servers.
- A mailbox on a Blackberry mobile device contains many folders. For example, the mailbox contains more than 5000 folders.
- Email message delivery to the mailbox on a BlackBerry mobile device is delayed.
- It takes longer than expected to scan a folder hierarchy in the mailbox. For example, before you install Update Rollup 4 for Exchange Server 2010 SP2, a scan of a folder hierarchy takes about 5 minutes. After you install Update Rollup 4 for Exchange Server 2010 SP2, a scan of a folder hierarchy takes about 30 minutes to 1 hour.
- The Microsoft Exchange Information Store process (Store.exe) on the Exchange Mailbox server uses excessive CPU resources.
- Some BES event log entries are logged on the Exchange Mailbox server. Before you install Update Rollup 4 for Exchange Server 2010 SP2, few entries are logged, or no entries are logged.
- Some events are logged in the BlackBerry Messaging Agent (MAGT) log. These events resemble the "Busy Working" threads that are described in the following article in the BlackBerry Knowledge Base:
Install Exchange Server SP2 RU 6 when it becomes available.
If there are less than 15 agents on the BES, add more agents to the BES. The maximum number of agents is 15.
Reduce the number of folders in the mailbox.
If the mailbox contains many folders (for example, more than 500 folders), move the mailbox to its own instance of BESAgent.exe.
