Unable to Mount Exchange 2013 Database

Question

_{Saturday, September 17, 2016 9:55 PM}

When I try to mount the exchange database I receive the following:

error

Failed to mount database "Exchange2013". Error: An Active Manager operation failed. Error: The database action failed. Error: Operation failed with message: MapiExceptionDatabaseError: Unable to mount database. (hr=0x80004005, ec=1108) Diagnostic context: Lid: 65256 Lid: 10722 StoreEc: 0x454 Lid: 1494 Remote Context Beg Lid: 45120 dwParam: 0x495E49 Lid: 57728 dwParam: 0x495FB1 Lid: 46144 dwParam: 0x49602E Lid: 34880 dwParam: 0x49602E Lid: 34760 StoreEc: 0xFFFFFDF0 Lid: 41344 Guid: d8f4016a-7694-48c1-be7a-dee192166b6e Lid: 35200 dwParam: 0x6FFC Lid: 46144 dwParam: 0x496781 Lid: 34880 dwParam: 0x496781 Lid: 54472 StoreEc: 0x1388 Lid: 42184 StoreEc: 0x454 Lid: 1750 Remote Context End Lid: 1047 StoreEc: 0x454 [Database: Exchange2013, Server: exchange.XXXXXXXXXXXXXXXXXXXX.com]

Here's the bad news. It looks like one of my team deleted several log files. Since the log files were deleted more than a day ago, I don't have a backup. I only have a full backup from after the deletion happened.

So, basically, I need to know how to mount an *.EDB file that has missing log files.

I am a novice, and not super technical. Probably know just enough to get myself into trouble.

Any help is greatly appreciated.

Hi Mark,

Check with eseutil /mh <edb path> if database is not in clean shutdown, if not just run with /p switch to get it in clean shutdown Once it come to clean shutdown state, then try moving the checkpoint and logs to a temporary location and mount database to see whether it works.

Given the error message, here also a solution for this issue in : Problem in Exchange 2013 Database mount failed!

For ESEUTIL explanation please refer to the article: Not able to mount database - Eseutil.exe to the rescue

Jason's give you great information, however a few points of clarification

1. If the /MH shows the DB as clean then as Jason says MOVE the logs and CHK file to an alternate location and attempt the mount process again

2. If the MH does not result in a clean state then yes you will need to run a /P against the DB, however before doing so I would strongly suggest that you make a copy of the EDB since the /P is a destructive process that examines each page in the DB and then throws the entire page away if a single error is within.

Now you said that an associate removed/deleted logs correct?  Can you expand on this i.e. was the DB up when this occurred and then it went down or??

Search, Recover, & Extract Mailboxes, Folders, & Email Items from Offline Exchange Mailbox and Public Folder EDB's and Live Exchange Servers or Import/Migrate direct from Offline EDB to Any Production Exchange Server, even cross version i.e. 2003 --> 2007 --> 2010 --> 2013 --> 2016 with Lucid8's DigiScope http://www.lucid8.com/product/digiscope.asp
