Installation Notes:

If you haven’t installed Exchange Server yet, you can use the info at Quicker Exchange installs complete with service packs and rollups to save you some time.

Microsoft Update can’t detect rollups for Exchange 2010 servers that are members of a Database Availability Group (DAG). See the post Installing Exchange 2010 Rollups on DAG Servers for info, and a script, for installing update rollups.

Update Rollups should be applied to Internet facing Client Access Servers before being installed on non-Internet facing Client Access Servers.

If you’re installing the update rollup on Exchange servers that don’t have Internet access, see “Installing Exchange 2007 & 2010 rollups on servers that don’t have Internet access” for some additional steps.

Also, the installer and Add/Remove Programs text is only in English – even when being installed on non-English systems.

Note to Forefront users:

If you don’t disable Forefront before installing a rollup or service pack, and enable afterwards, you run the risk of Exchange related services not starting. You can disable Forefront by going to a command prompt and navigating to the Forefront directory and running FSCUtility /disable. To enable Forefront after installation of a UR or SP, run FSCUtility /enable.

Installation Notes:

If you haven’t installed Exchange Server yet, you can use the info at Quicker Exchange installs complete with service packs and rollups to save you some time.

Microsoft Update can’t detect rollups for Exchange 2010 servers that are members of a Database Availability Group (DAG). See the post Installing Exchange 2010 Rollups on DAG Servers for info, and a script, for installing update rollups.

Update Rollups should be applied to Internet facing Client Access Servers before being installed on non-Internet facing Client Access Servers.

If you’re installing the update rollup on Exchange servers that don’t have Internet access, see “Installing Exchange 2007 & 2010 rollups on servers that don’t have Internet access” for some additional steps.
