Update:
Exchange 2010 SP1 Rollup 4 has been removed from the Download Center due to issues. If you have it already installed, you can uninstall it or contact Microsoft Customer Support and request interim update KB2581545 (KB article will be published later). It appears a fixed version of SP1 RU4 won’t be released and instead will be directly superseded by SP1 RU5 scheduled for August.
Update Rollup 4 for Exchange 2010 Service Pack 1 is now available for direct download (see below for links). It will be made available via Microsoft Update on July 28.

- KB2519359 Unable to Create a ‘Reply With’ Rule on Public Folders Even With Owner and Send As Permissions
- KB2394554 Generating DSN fails if original mail uses non-support encoding charset.
- KB2490134 Outlook 2007 does not deliver “Delayed Delivery” Messages against an Exchange 2010 Server in Online mode with any additional Transport loaded in the Outlook Profile
The next update rollup is scheduled for release in August 2011.
