Rollup 4 for Exchange Server 2010

The team has released Update Rollup 4 for Exchange Server 2010 RTM (KB 982639)

KB 982639 lists all the fixes included in this rollup. Here are some of the product improvements and critical fixes we’d like to call out starting with 5 improvements we made to prevent crashes in very unique scenarios.

  • KB 980852 The RpcClientAccess process on an Exchange 2010 server crashes when you access a mailbox by using a MAPI application
  • KB 979801 An error message is generated in Exchange 2010 when you use Troubleshooting Assistant
  • KB 980364 The Transport service on an Exchange 2010 server crashes when a certain message is processed
  • KB 980353 A MAPI application that is used to access Exchange 2010 mailboxes crashes when the application accesses an address book
  • KB 979790 An IMAP4 client crashes when accessing an Exchange 2010 mailbox

We corrected a few replication issues some of you encountered.

  • KB 980149 The Add-MailboxDatabaseCopy command fails when it is used to add a database copy to a Database Availability in an Exchange 2010 environment
  • KB 981961 Event ID 4033 is logged and the /Busy replication from an Exchange 2003 server to an Server 2010 server fails
  • KB 979921 You cannot replicate a from one Exchange 2010 server to another, and Event ID 3079 is logged on the target server

Important:
Microsoft does not detect Update rollups on Exchange 2010 Mailbox servers that are part of a database availability group (DAG).
