Hi,

Could you please provide more details regarding the question?

Are you saying you want to move a dismounted database to another server? If you want to change the database to a different path, you could use 'Move Database Path' option in Exchange Management Console.

http://exchangeserverpro.com/move-exchange-2010-database-folder/

Please let me know if you have Database Availability Group (DAG) configured in your environment. Once the database is dismounted, mailboxes in that database will not be able to send/receive mails. All client connection with mailboxes in the database will be disconnected. If you have DAG configured, replication will be stopped for the dismounted database. There will not be any process accessing the dismounted database.

Could you please let me know what errors you are getting? Since you are keeping the database dismounted, you would keep on getting alerts regarding that. Another option would be to take backup of the database and keep the backup or you could export mailboxes in the database as PST files and keep it for future use.

Yep, it sounds like you'll need to backup your database with an Exchange-aware backup application, then restore the database to another server. May I ask why you would want to store a dismounted database on another server though? Is the plan to be able to mount the database when you require access to it? If so, why not just leave the database mounted all the time to avoid the error messages being generated in the logs?

1) You need a VSS aware Exchange backup software to truncate the logs. Manual truncation is not recommended as it will not update the checkpoint file, and you will have issues when doing a restoration
2) You cannot just move a database manually, but instead use a set of commands:

Move-DatabasePath <GUID of DB> -EdbFilepath <path here> -LogFilePath <path here>

That error message is by design whenever you have a mailbox database dismounted. The errors will persist until you either remove the database or remount it again.

I have a third party program, that program read the edb and export the information but when scanning the database dismounted, the email server stop sending and received
As mentioned above, use an Exchange aware backup platform to back up your database. You should then use the third party program along with the backup software to export any information, as opposed to using the third party program with the live (but dismounted) edb file.

I extracted the data, and the Content Index service says the database is offline...

How much free space do you have on the volume that contains the logs for this database? Are you running backups, or have circular logging on (I am not recommending circular logging)?

But did you dismount the database or is it dismounting on its own? If its dismounting on its own and you have 17GB free, then I would recommend creating a new mailbox database on a separate set of disks (so a different volume, different set of hard drives) and moving the users there.
