Here are some handy commands to do with Mailbox Databases, from retrieving information, to moving log folders. I highly suggest separating the Logs and databases on to different drives when doing a fresh install of Microsoft Exchange 2016. Also ensure you have a D:\ data drive and not a DVD-Drive, as Exchange by default installs some additional log folders here.
Commands to retrieve database information.
– Get-MailboxDatabase | fl Name,Edbfilepath,logfolderpath
Create a New Mailbox Database
– New-MailboxDatabase -Name “DB01” -EdbFilePath D:\Exchange Database\DB01\DB01.edb
Rename Mailbox Database Command
– Set-MailboxDatabase “Mailbox Database Name” -Name DB01
Move Exchange Database and Log files to a new Location
– Move-DatabasePath DB01 -Edbfilepath “D:\Exchange Database\DB01.edb” -LogFolderpath “D:\ExchangeLogs\Database Logs\DB01”
Hope this was helpful,
