You would have noticed that when WSUS detects Exchange 2007 SP1 UR5 it has 1364MB in size whereas manual download on Microsoft site has only 66MB for English language.
You may verify it in Microsoft Update catalog.
Reason: There could be a mistake in the automation part which creates the Microsoft Update XML for WSUS and resulted in this issue.
Issue: The WSUS server that only wants supported language patches (for example just English patches), cannot get requested updates from Microsoft Updates site and then be forced to download updates for all languages which is 1364MB in size.
This will be fixed in the next Update Rollup meanwhile you are concerned about this UR5 then there are two options…
- Once UR5 is deployed on all servers through WSUS, remove the rollup from WSUS server to release the space.
- Download Exchange 2007 SP1 UR5 manually and update the Exchange servers to avoid full download on WSUS server.
