We had an issue where a recent Windows update broke the Exchange Server, luckily booting into safe mode and removing it resolved the issue, however although the databases mounted okay, there was one that did not.<\/p>\n\n\n\n
We attempted the typical ESEUTIL steps because it was reporting “dirty shutdown”, and got the database back to a “Clean Shutdown” state however it still would not mount giving errors as below:<\/p>\n\n\n\n

To resolve the issue in this case we renamed the transaction log directory used by the database to add “-old” to the end, then created a new directory with the original name.<\/p>\n\n\n\n
Then attempted to mount the database with:<\/p>\n\n\n\n
[PS] Y:\\Inactive-Mailboxes-1601a>Mount-Database inactive-mailboxes-1601a<\/code><\/pre>\n\n\n\nThe database then mounted successfully without the error. It appears that something within the log file chain (which should have been detached) was causing an issue, as the database was showing as clean shutdown, its essentially detached from its log chain so these log files are not supposed to be needed to mount. Making sure it can’t by moving the old files away seems to have resolved it.<\/p>\n\n\n\n
