Database status Bad copy count "1" -Exchange 2013

I am using exchange 2013. There are two mailbox servers which are in DAG. Database is mounted and healthy. All seems good. To configure a DR Site, I created an exchange 2013 on azure cloud and synced one database. When I started second database sync, it got failed saying below error. When I check database status, It shows me "Bad copy count" status is 1. While database is mounted and healthy.

error

The seeding operation failed. Error: An error occurred while performing the seed operation. Error: An error occurred while communicating with server 'TTAEXCH2013C1'. Error: Unable to read data from the transport connection: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. [Database: MailboxDB_Users3, Server: Exchange2013-DR.TTA.MUMBAI.COM]

Hi Arif,

BAD count means that your third copy of effected mailbox database is not healthy or not in properly created in Azure Exchange server. You may delete the passive copy of database on Azure Exchange server and then retry to add it.
