Exchange Server - Transaction logs - unmounted DB

Rahim Mohamed Munibuddin

In Exchange 2016, the default DB had problem mounting. So we created another new DB and it is working. But even for the default DB which is not mounted daily transaction log files are created. I do not know why. Is it OK. When the DB is not mounted how the transaction log files are generated?

Do you have any mailboxes in that db?.
Make sure you have moved arbitration mbxes to your new db

@Rahim-Mohamed-Munibuddin & @Engin-Altug , I hope all is well. If you are no longer using the default db, as long as you ensure that ALL of the associated mailboxes have been removed, you can delete it. There are several mailboxes that may still be associated and causing logs to be created.

Steps are below:

To move the arbitration mailbox, type the following command –

Get-Mailbox -Database “Mailbox Database 5865324204” -Arbitration | New-MoveRequest -TargetDatabase “NewDatabase”

To move monitoring mailboxes, type of the following command –

Get-Mailbox -Database “Mailbox Database 5865324204” -Monitoring | New-MoveRequest -TargetDatabase NewDatabase

To move AuditLog mailboxes, type the following command –

Get-Mailbox -Database “Mailbox Database 5865324204” -AuditLog | New-MoveRequest -TargetDatabase NewDatabase.

After successful deletion of all the associated mailboxes, you can finally delete the default Exchange mailbox database. It will confirm whether you want to delete it or not. Click Yes.

Good Luck !!!

Cheers,
