What you do is locate the location of your stores..
If my case they are located here: d:\exchsrv\MDBDATA\
Move all files except the .EDB and .STM files to a temp folder.
Check the .EDB files for clean shutdown or not by using this command.
d:\exchsrv\bin\eseutil /mh d:\exchsrv\MDBDATA\priv1.edb
browse up and locate the STATUS line.
If this does not report back clean shutdown.. then you have a dirty shutdown.
To fix the problem file run the following command d:\exchsrv\bin\eseutil /p d:\exchsrv\MDBDATA\priv1.edb
When everything has completed, try and mount the stores again. This should probably solve your problem.
