Not able to Add Mailbox Database Copy

When you running the command Add-MailboxDatabaseCopy -Identity 'Mailbox Database 0997342447' -MailboxServer 'EX01' -ActivationPreference '2' it's failing with error. (see Figure 1)

The problem is that you have Database on D: drive on Server 2 which is the Passive node and on Active node the Database is on E: drive.

To fix the issue, you just need to change the location of the Database from D drive to E drive. You can use  Exchange Management Console and if fails than, use Adisedit.msc tool to change the location.
Go to Adsiedit.msc...>Configuration...>Services...>Microsoft Exchange...>ORG...>Administrative Group...>Exchange Administrative Group...> Database, right click on the Database "Mailbox Database 0977108011"and go to properties and check the attribute "msExchEDBFile" and change the location from D: drive to E: Make sure you change the location physically as well ;) (see Figure 2)

Add-MailboxDatabaseCopy command will complete successfully.
