The Exchange team has released update rollup 5 for Exchange 2010 SP2 deployments.
Exchange 2010 SP2 is the minimum requirement for this rollup. As always, it is a cumulative rollup and can be applied without installing the previous ones. Forefront needs to be disabled before installing the update by running fscutility /disable and enabled after the installation.
The required services are restarted during the rollup installation and hence a server restart is not required.
Download the rollup here and a list of issues fixed in UR5 is explained here.

UR5 can no longer be downloaded due to bug that affects DAG’s. Stay tuned for Version 2.

Hi Leon,
The UR5 has a bug in it and hence has been pulled off. Wait for v2

Looks like the update is back out there now, but it isn’t called v2. I wonder if it is okay now.

V2 is ok Matt.
