Update Rollup 1 for Exchange Server 2010 Service Pack 1 is now available to fix public folder problems and other
flaws that have come to light since the release of SP1 in August. For many IT pros, the rollup also signals that it’s safe to use SP1, just as the release of Service Pack 1 for Exchange Server 2010 gave the green light for upgrading, said Mike Crowley, Exchange administrator and Microsoft MVP with the technology integration company Planet Technologies Inc.
The first rollup for Exchange Server 2010 SP1 fixes the server’s inability to replicate a public folder from one Exchange 2010 server to another. It also addresses access issues such as the inability to view updated content in an Exchange Server 2010 public folder.
The rollup also resolves problems encountered when a user’s email address is updated unexpectedly after running the Update-Recipient cmdlet on an Exchange 2010 server along with troubles encountered when removing a sender's email address from the recipient list in a redirected email message. IMAP4 clients will also be able to send email messages with large attachments in mixed Exchange Server 2010 and Exchange Server 2003 environments.
Update Rollup 1 for Exchange Server 2010 SP1 can be downloaded from the Microsoft Update website. Rollup 2 for Exchange Server 2010 SP1 is scheduled for release in early December.
