A quick notice on a potential issue with Exchange 2007 SP3 and database corruption after installing Rollup 3. The issue may occurs in the following situations:
- When transaction log replay is performed by the Replication Service as part of ensuring the passive database copy is up-to-date;
- When a database is not cleanly shut down and recovery occurs.
Because of this, Rollup 3 for Exchange 2007 was pulled and you’re advised to uninstall Rollup 3 on Exchange 2007 Mailbox and Transport servers. For more information, consult the post on the Exchange Team’s blog here.
Note that the issue may affect all Mailbox servers, clustered or standalone, so you’re also advised to uninstall RU3 on standalone Mailbox servers. For those with the issue on CCR or SCC setups, it requires reseeding or restoring from backup so plan accordingly.
Looking at the issues with latest Rollups for Exchange 2010 and 2007, it gives to think about the quality control process or if the Exchange team’s priorities perhaps lay somewhere else (Office 365?).
