Move and rename the default Exchange Server 2016 mailbox database

Whenever Exchange server migration 2016 is installed, it creates a default mailbox database automatically. This database is created in default Exchange installation location i.e. in drive ‘C’. But instead of retaining these default mailboxes database, one needs to move it as only OS should be installed in the ‘C’ drive.

Run the following to find the name of the default database.

Get-MailboxDatabase -Server “mailbox04”

Open Exchange Admin Center checked the Databases and Database with Default names.

Rename the database:For renaming the database following are the commands required that need to be run.
