1- Restore the Mailbox Store (.edb file) from the backup and also the log files!
2- Go to the folder where you put the .edb file . We need now to check if the database was clean shutdown or dirty shutdown.
[PS] S:\Data>eseutil.exe /mh SG1.edb
This database is now in Clean Shutdown, but is was in Dirty Shutdown condition.
Next lets see if our log files are ok!
[PS] S:\Data>eseutil.exe /mh S:\Recovery\RDB1\E02
(Being E02 my prefix for the logs and my log are on S:\Recovery\RDB1\)
This is important since our log files must be ok! This is Full backup, plus the incremental!
3 - Now we try to recover the database with the log files.
In my case:
[PS] S:\Data>eseutil.exe /r E02 /l S:\Data\RDB1\ /a /d S:\Data\SG1.edb
If it was successfully check again the stat of the DB with eseutil.exe /mh
If still says dirty go to the folder where your edb file is (mine S:\Data) and run following command:
[PS] S:\Data>eseutil.exe /p SG1.edb
WARNING: This will take a long time and will lock the transaction log file! Be advised! My edb file with 335GB took about 13 hours to complete, but in the end it was in clean shutdown!!! :) URRA!
4- Now we have a database cleanly shutdown so we will mount it.
[PS] S:\Data>New-MailboxDatabase -Recovery -Name "RDB" -Server EXCH-MB1 -EdbFilePath S:\Data\SG1.edb -LogFolderPath S:\Data\E02
Open Exhange Management Console and check if the RDB is mounted and green! :)
5- Finally we will recover the mailbox we want. Create a normal Mailbox, name it whatever you want, i call it Recover, give to you full access on it! Add this to your outlook account!
And now we will restore the mailbox we want to a FOLDER inside the mailbox Recover we add previously created... You could restore to you own mailbox since it will create a folder and put all the folder of the mailbox to be recovered inside. But i prefer to separate things!
This command is tricky in the switches, the IDENTITY is the mailbox where you will put the recovered mailbox and RecoveryMailbox being the one to be restored!
[PS] S:\Data>Restore-Mailbox -Identity "Recover" -RecoveryMailbox "JohnDoe" -RecoveryDatabase RDB -TargetFolder "JohnDoeRecover" -Confirm
Wait until it finishes!
Now you can go check your Recover mailbox and there will be a folder name JohnDoeRecover with all the email and folders inside!
Hope this helps, any question put in the comments!
