Last week, the MSExchange team blog announced the re-release of Update Rollup 3 for Exchange 2007 SP3. The first release had some issues that could cause database corruption under certain circumstances.

This week the re-releasing continues, this time with Exchange 2010 instead of Exchange 2007. Microsoft has announced the re-release of Update Rollup 3 for Exchange 2010 SP1. The issue with the prior version of the rollup was with Blackberry services, which we at DidItBetter know is likely to affect a number of our customers.

You can find the details at their blog:
