I am getting following error and unable to mount the database

Failed to mount database 'Mailbox Database'.

Mailbox Database
Failed
Error:
Failed to mount database 'servername\First Storage Group\Mailbox Database' after a lossy failover occurred because of the current setting for AutoDatabaseMountDial. You must run Restore-StorageGroupCopy before you can mount the database.

Why are you wanting to mount the db without using restore-storageGroupCopy?

Hi,

According to the error, you have to run Restore-StorageGroupCopy before you can mount the database.

Please refer to the following articles to execute it:
