On a SBS2003 server, we had the Exchange server bump into the 16GB database limit. I installed Exchange SP2 and made the registry changes to increase to 75GB limit (hard drive space is not an issue at all). The process seemed to go smoothly -- dismounted and remounted the store -- no problems encountered -- until the next scheduled backup.
Now Windows SBS backup reports " WARNING: Portions of "\Program Files\Exchsrvr\MDBDATA\priv1.edb" cannot be read. The backed up data is corrupt or incomplete." So it looks like the private store got corrupted during the time it was over-sized. There have been some new emails and new appointments created in the public folder calendars since the re-sizing occurred, so I don't want to restore from backup if I can avoid it at all. I do know that some data may be truncated, but that will still be less of an impact than restoring the data (in particular the public folders).
What steps should I follow (step by step please, not just a KB article number) to perform a soft or hard recovery on the Exchange data store(s)? Is there something else I need to do in addition to running ESEUTIL?
