Exchnage 2007 mailbox store that will not mount, error 1216, MapiExceptionJetErrorAttachedDatabaseMismatch

I'm working on a server that I have not maintained before that has a dismounted mailbox store in SBS 2008 (so it runs Exchange 2007).  When I try to mount the store, I get:

Exchange is unable to mount the database that you specified. Specified database: SOLAR1\First Storage Group\Mailbox Database; Error code: MapiExceptionJetErrorAttachedDatabaseMismatch: Unable to mount database. (hr=0x80004005, ec=-1216)

I've run an eseutil /p and an eseutil /d on the database.  I still get the same error.

If I run eseutil /mh, I get this:

If I run isinteg -s solar1 -fix -test alltests, it returns:

Databases for server solar1:

You have selected First Storage Group / Mailbox Database.
Isinteg cannot initiate verification process.

In the event log, I see this after I run "isinteg -s solar1 -fix -test alltests":

event id 494:
MSExchangeIS (2092) First Storage Group: Database recovery failed with error -1216 because it encountered references to a database, 'D:\Program Files\Microsoft\Exchange Server\Mailbox\First Storage Group\Mailbox Database.edb', which is no longer present. The database was not brought to a Clean Shutdown state before it was removed (or possibly moved or renamed). The database engine will not permit recovery to complete for this instance until the missing database is re-instated. If the database is truly no longer available and no longer required, procedures for recovering from this error are available in the Microsoft Knowledge Base or by following the "more information" link at the bottom of this message.

event id 454:
MSExchangeIS (2092) First Storage Group: Database recovery/restore failed with unexpected error -1216.

event id 9518:
Error 0xfffffb40 starting Storage Group /DC=local/DC=domain/CN=Configuration/CN=Services/CN=Microsoft Exchange/CN=First Organization/CN=Administrative Groups/CN=Exchange Administrative Group (FYDIBOHF23SPDLT)/CN=Servers/CN=SOLAR1/CN=InformationStore/CN=First Storage Group on the Microsoft Exchange


Here's what I think I'm seeing - the database isn't mounted because Exchange seems to think the database isn't in the proper folder (see event id 494 above).  However, the database is clearly there.  See screen shot below.  Any ideas on what to try next?  I'm a rookie at Exchange database recovery.  Minus eseutil, I've never had to run anything really.

Please move all the other log files and folders from the database edb file location to another folder.
just keep only the .edb file and move all the log files to another folder and try mounting the stores.

Please check it out and revert back if you have any issues.
And also please enable the option "This database can be overwritten by a restore".
It will be the properties of the mailbox store.
Please check that out and revert back if you have any issues.

Damn - that was easy.  I removed all the log files and then checked the box to allow the database to be overwritten by a restore and voila, the mailbox store mounted.
Duta GoodnewsCommented:
I had exactly the same today and just by moving the log files and marking the database to be overwritten by  a restore does the magic.

Thank you so much. I really appreciate.
I did the same steps as mention above and MY DATABASE mount and production  Exchange server working Fine now. Thanks a lot for the  for your informative  steps & procedure..
