Update Rollup 5 for Exchange 2007 SP1 (announced a few days ago) has been released. The rollup is available on the Download Center here:
The rollup will go live on Microsoft Update in 2-3 weeks from now (will be announced here). Localized versions for all supported languages are now available on Download Center.
KB 953467 has more details about this release and the included fixes.
We specifically want to call out two fixes related to the overall installation experience:
1) Service startup issue described in KB 944752 and a previous blog post.
2) Blank OWA logon page after installation of rollups 3 and 4, if you have modified logon.aspx file
