What seems to be the issue? Have you restored the database back to your new exchange install, and can't mount the database?

If you are just having issues mounting the database it is probably due to your database backup is in a "dirty" shutdown state. You will need to use eseutil to repair the database.

Use eseutil /mh to view if the database (.edb) file is in a dirty shutdown state.
User eseutil /r which will attempt to recover the database errors and

If eseutil /r does not work for you, you can use eseutil /p which re preform a repair on your database and then you should be able to re-mount the database on your new Exchange server.

What did you use to backup your Exchagne Server prior to the failure? You can use Windows Server backup to accomplish this. You can also use ESEUTIL in Restore mode to restore your database.

ESEUTIL Restore Mode - http://technet.microsoft.com/en-us/library/aa997478(v=exchg.65).aspx

I have checked and  restored the database. I Now, when i tried to open any user in recipients tab I'm getting the below error.
The object promptit.com/Users/Muhsin PM has been corrupted, and it's in an inconsistent state. The following validation errors happened:
Database is mandatory on UserMailbox.

Since you have restored the database have you rebooted the server?

Also this error message usually relates to a permission issue with the Discovery Search Mailbox.

Thanks for your comment. After rebooting I'm unable to open the OWA, Outlook and ECP also not opening. Looks like I'm back at certificate issue which was at the previous Exchange.

I had restored the old mail box successfully (As recovery database 4 GB Data). But still I'm not getting the old mails from the old mailbox stored in the recovery database

It is possible that they are corrupt from the backup. Do you have another clean backup that you could restore?

Have you used the get-mailboxstatistics -database <recovery database> to see if all of the mailboxes are listed? From there you can restore the mail items to a non-recovery database.
