Dear Exchange 2013 users,

We have exchange environment of version in 2013.

We have main site and DR site. Adding database copy has failed in DR site.

The following getting.

error
EMPDB3
The seeding operation failed. Error: An error occurred while running prerequisite checks. Error: The specified database isn't configured for replication and therefore cannot be used to perform seed operations. [Database: EMPDB3, Server: SRVINFDRMBX01.x.x.x]

Kindly help how can resolve this issue.

try forcing AD replication between the two sites, and then create teh DB again.

Hi Ashraf,

Thank you for your question.

This issue may occur because the Add-MailboxDatabaseCopy cmdlet utilizes different DCs (Domain Controllers) in different parts of the task and the DCs may inconsistent due to site replication delay.

We could refer to Hinte's advice to force AD replication. We could refer to the following link:

If there are any questions regarding this issue, please be free to let me know. 

Best Regard,
