Edit: Update Rollup 18 is now available for Exchange 2010 SP3 see the post Exchange 2010 SP3 Update Rollup 18 installation tips.
On 16th June Microsoft released the Exchange 2010 SP3 Update Rollup 10.
I’ve installed this on my test SBS 2011 server, it took just 21 minutes 23 seconds from start to finish, more than twice as long as the last update rollup, but my test rig was running a few other processes at the same time, so I wouldn’t expect this to take much longer than this in production.
The new update has been available for a couple of weeks now, and I have not seen any issues reported with it so I suspect it is safe to deploy in your production environment.
The Update Rollup 10 for Exchange Server 2010 SP3 contains the fixes for the security issue that is described in KB3049853 and the following Microsoft Knowledge Base (KB) articles:
- KB 3069055 Various DAG maintenance scripts do not work in an Exchange Server 2010 environment
- KB 3057422 “MapiExceptionNoAccess: Unable to query table rows” error and some mailboxes cannot be moved
- KB 3056750 Exchange ActiveSync application pool crashes in an Exchange Server 2010 environment
- KB 3054644 “The item no longer exists” error when you access an archive mailbox in Outlook Web App in Exchange Server 2010
- KB 3051284 Event ID 4999 is logged and MSExchangeServicesAppPool crashes in an Exchange Server 2010 environment
- KB 3049596 Event ID 4999 is logged and remote procedure call Client Access service crashes in an Exchange Server 2010 environment
- KB 2964344 MSExchangeRPC service stops working intermittently in Exchange Server 2010

While looking for others experience of installing the update rollup I’ve come across a few suggestions that might help speed the install up and a few best practice tips.
1. Reboot the server prior to installing the update rollup. If it has been up for a while a reboot will make sure it is in a know good state.
2. Run the update from an elevated command prompt.
3. In Internet Explorer, deselect “Check for Publisher’s certificate” and “Check for server certificate revocation”, from Internet Options, Advanced tab, Security options.
4. Disable antivirus software.
5. Have a full backup and a system state backup of the server.
6. Make sure the SBS console is closed if installing the update on SBS 2011.
7. Backup any OWA customisations you have in place.
8. Stop any Backup Exec services if you have it running locally.
While the update is installed it will automatically stop Exchange and IIS services, and restart them again once complete.
Once the update has finished, remember to undo the changes made in steps 3 and 4 above.
