Update Rollup 5 for Exchange 2007 SP1 is now released

The rollup is available on the Download Center here:

It will be available on Microsoft Update in 2-3 weeks from now (we will announce that). In case that you need a fix in a language that is not available right now, they are in the pipeline already so please check back.
The KB article describing this release as well as fixes is here: http://support.microsoft.com/?kbid=953467
We specifically want to call out two things fixed regarding the overall installation experience:
1) Service startup issue as described in KB http://support.microsoft.com/kb/944752 as well as our previous blog post.
The rollup installer will now make the required modifications to the config files, even create new config files if not found. If customers have already modified the config files and have a generatePublisherEvidence setting, it will be left intact. Note that you still need the right version of .NET (see KB 944752) for the fix to take effect.
Un-installation of the rollup will not rollback the addition of generatePublisherEvidence to config files.
2) Blank OWA logon page after installation of rollups 3 and 4, if you have modified logon.aspx file
The rollup installer will now overwrite any OWA script files if required to ensure proper operation of OWA. You will need to redo any customization after installation of the rollup.
