A known issue with Exchange 2010 SP3 RU1 Setup
You cannot install or uninstall Update Rollup 1 for Exchange Server 2010 SP3 on the double-byte character set (DBCS) version of Windows Server 2012 if the language preference for non-Unicode programs is set to the default language. To work around this issue, you must first change this setting. To do this, follow these steps:
- In Control Panel, open the Clock, Region and Language item, and then click Region.
- Click the Administrative tab.
- In the Language for non-Unicode programs area, click Change system locale.
- On the Current system locale list, click English (United States), and then click OK.
After you successfully install or uninstall Update Rollup 1, revert this language setting, as appropriate.
We have identified the cause of this problem and plan to resolve it in a future rollup, but did not want to further delay the release of RU1 for customers who are not impacted by it.
A known issue with transport rules after E2010 SP3 RU1 is installed
We have an issue where the messages stick in poison queue and transport continually crashes after this rollup is applied.
We have gathered enough information and have determined the issue. Specifically, the issue is caused by a transport rule (disclaimer) attempting to append the disclaimer to the end of HTML formatted messages. When this occurs, messages will be placed in the poison queue and the transport service will crash with an exception. We are investing resources to develop a code fix. You can either disable or reconfigure the disclaimer transport rule.
