Exchange Server 2010 SP1 rollup 6 released, decreases crashes

Update rollup 6 for Exchange 2010 SP1 fixes 29 user and internally spotted issues. Six of those fixes stop unexpected Exchange 2010 SP1 crashes.

The Microsoft Exchange team released update rollup 6 for Exchange Server 2010 Service Pack 1 with relief for serious crashes and fixes for a number of bugs reported since the release of rollup 5 in August.

While there are critical fixes in rollup 6, most of them solve minor problems.

“It feels like they started to dig into the lower-priority bugs that have been around for a while,” said Rob Sanfilippo, an analyst with the Kirkland, Wash.-based Directions on Microsoft. “The previous rollups addressed higher-priority problems. These are very specific situations that probably aren’t encountered very often.”

Of the 29 fixes in rollup 6, one of the most important fixes helps administrators who could not open the Exchange Management Console (EMC) or the Exchange Management Shell (EMS) in an Exchange 2010 SP1 environment, which caused an Exchange 2010 server to crash.

Additionally, there were problems with Microsoft Exchange Information Store service crashes due to corrupt folder views on mailbox servers and antivirus applications.

Another important fix was an issue concerning role based access control (RBAC) assignees. Prior to deploying RU 6, a role assignee could unexpectedly run the Add-MailboxPermission command or the Remove-MailboxPermission command on an Exchange 2010 SP1 server outside the role assignment scope. Though small, this was a security hole that administrators needed Microsoft to close.

This rollup also fixes a couple of problems with Outlook Web App (OWA), such as the inability to disable the Exchange ActiveSync Integration feature in OWA Premium clients.

This is likely the final rollup update for Exchange 2010 SP1 before the scheduled end-of-2011 Exchange 2010 SP2 release. Exchange Server 2010 SP2 will include Outlook Web App Mini, a hybrid configuration wizard for companies moving to Office 365 and address book policies, among other things.

“Things will really get interesting when SP2 comes out. We’ll see how [SP2] affects stabilization,” Sanfilippo said.
