We're proud to announce that Microsoft Dynamics CRM 2011 Update Rollup 6 released Thursday, Jan. 12th, 2012!

Microsoft Dynamics CRM 2011 Update Rollup 6 Podcast

PLEASE NOTE:

Note: The CRM 2011 Update Rollup 6 packages, originally released on Jan. 12th, 2011, were recalled early Jan. 13th. If you have downloaded any of these packages (build 1985) please discard them and download new versions available now (build 9692.1992). The new packages were released Saturday, Jan. 21st.

If you did new installs with the Update Rollup 6 "slipstream" packages that were released (these would be the packages that include the full install bits as well as Update Rollup 6) you will get an error trying to patch those components to the new Update Rollup 6 build. This Knowledge Base article describes the issue:

http://support.microsoft.com/kb/2668504 . This Knowledge Base article is live, as well as the updated Update Rollup 6 KB article: http://support.microsoft.com/kb/2600640.

The only workaround is to reinstall if you happened to use the Update Rollup 6 slipstream builds. For server you can connect to existing databases on the reinstall. The reinstall goes for any of the components that you installed with the Update Rollup 6 slipstream builds, (Client, Router, etc.). If you do not reinstall you will not be able to patch to the re-released Update Rollup 6 packages or future Update Rollups, as Update Rollup 6 represents a new baseline.

Update Rollup 6 Build number:
5.0.9688.1992

Note: Update Rollup 6 cannot be uninstalled. Specific database updates are applied during Update Rollup 6 installation that will not let you uninstall Update Rollup 6. You should back up your databases and application servers before you install this update.

Note: Update Rollup 6 establishes a new servicing baseline. This will enable uninstalls of some future CRM 2011 Update Rollups, but this also means that Update Rollup 6 will be a prerequisite for installation of post-Update Rollup 6 Update Rollups.

Note: As Update Rollup 6 is cumulative, containing all changes released in earlier Update Rollup releases, it also contains the Dynamics CRM Q4 Service Update features released via Update Rollup 5.  Some of these features include:

• Outlook Client Updates:
• Enhancements to the Reading Pane
• Asynchronous promotion for tracked emails
• Dialog Enhancements
• Data Visualization Enhancements:
• Chart Designer Enhancements
• New Chart Types
• Data Management Enhancements to:
• Auditing
• Duplicate Detection
• Activity Feeds
• Listening in on important activities in Social Media that take place around the people, accounts, contacts, leads or opportunities that you care about, including a Windows 7.5 phone application: "Business Hub"
• Update Rollup 5 does not install Activity Feeds:
• New organizations on CRM Online will have this Solution automatically provisioned
• Existing Online or On Premise organizations must download and import the solution from the Dynamics Marketplace

Packages are available for download via: 

• The Update Rollup 6 Microsoft Download Center page (on Jan. 12th, 2012)
• The Microsoft Update Catalog (on Jan. 24th, 2012)
• The Microsoft Update detection / installation process (on Jan. 24th, 2012)
  • Note: Microsoft Dynamics CRM 2011 Updates will be pushed via Microsoft Update as Important updates
  • Client packages installed manually by downloading the packages and running install will require local administrator privileges. If the client packages are installed via Microsoft Update or SCCM (System Center Configuration Manager), they will not require local administrator privileges
  • Consider using Windows Server Update Services (WSUS) or similar software distribution technologies to distribute Dynamics CRM Update Rollups internally.  WSUS is a locally managed system that works with the public Microsoft Update website to give system administrators more control. By using Windows Server Update Services, administrators can manage the distribution of Microsoft hotfixes and updates released through Automatic Updates to computers in a corporate environment

Hotfixes and updates that you have to enable or configure manually

Occasionally, updates released via Update Rollups require manual configuration to enable them. Microsoft Dynamics CRM Update Rollups are always cumulative; for example, Update Rollup 6 contains all fixes previously released via Update Rollups 1-5 as well as fixes newly released via Update Rollup 6. So if you install Update Rollup 6 on a machine upon which you previously installed no Update Rollups, you will need to manually enable any desired fixes for Update Rollups 1-6:

• Update Rollup 1: no updates requiring manual configuration
• Update Rollup 2 for Microsoft Dynamics CRM 2011 contains the following update that you must enable or configure manually - details on enabling or configuring can be found in this Microsoft Knowledge Base article:
• 2535245 RetrieveMultiple optimization for basic depth needed for local and deep depth read privileges in Microsoft Dynamics CRM 2011
• Update Rollup 3: no updates requiring manual configuration
• Update Rollup 4: no updates requiring manual configuration
• Update Rollup 5: no updates requiring manual configuration
• Update Rollup 6 for Microsoft Dynamics CRM 2011 contains the following update that you must enable or configure manually - details on enabling or configuring can be found in this Microsoft Knowledge Base article:
• 2664150  Steps to clean up the PrincipalObjectAccess table in Microsoft Dynamics CRM 2011 after Update Rollup 6 is applied

Mismatched Update Rollup versions within a Microsoft Dynamics CRM deployment

In a scenario where you may be running many client workstations with Microsoft Dynamics CRM 2011 for Microsoft Office Outlook, a common question is whether it is supported to run mismatched versions. For example, where Update Rollup 5 has been installed on the CRM Server but the Outlook clients are still on Update Rollup 1, or where Update Rollup 1 is on the CRM server but due to updates available to the Outlook client you have decided to install Update Rollup 6 on the clients without installing Update Rollup 4 on the server.

The general rule of thumb is to try to keep the versions in sync as much as possible. However, it is permissible (though not recommended as a long-term solution) to run mismatched Update Rollup versions on Outlook client and server, as Microsoft does do some testing of such combinations.

However, regarding the other Update Rollups (for example Rollups for the Microsoft Dynamics CRM 2011 Email Router or Microsoft Dynamics CRM 2011 Reporting Extensions), it is not supported nor recommended to run mismatched versions. A best practice is to update these components at the same time you update your CRM Server.  Do the best you can to keep these Update Rollup versions in sync.

Internet Explorer 9 Compatibility

The Microsoft Dynamics CRM Sustained Engineering team extensively tested Microsoft Dynamics CRM 2011 against pre-release versions of Internet Explorer 9 and continues to address compatibility issues, as appropriate, against the RTW (Released to Web) version of Internet Explorer 9.  When necessary, Microsoft plans to release enhancements via future Microsoft Dynamics CRM 2011 Update Rollups to assure compatibility with Internet Explorer 9.

There are three CRM 2011 application compatibility fix released via Update Rollup 6 related to Internet Explorer 9:

• When you browse in the Microsoft Dynamics CRM web client by using Internet Explorer 9, Internet Explorer consumes excessive memory. Therefore, you experience slow performance
• When you use the Schedule feature in a service appointment in Microsoft Dynamics CRM 2011 with Internet Explorer 9, you receive the following error message:
• Can't execute code from freed script
• In Internet Explorer 8 or 9, ribbons are not displayed immediately when you open a form in Microsoft Dynamics CRM

There is a Update Rollup 5 fix for an expanding memory footprint issue associated with Internet Explorer, but it impacts all versions of Internet Explorer supported by CRM 2011  - those being Internet Explorer versions 7, 8, and 9.
