Description

Skype for Business Server makes extensive use of SQL Server databases such as the Central Management store and the Archiving database. These databases are set up at the same time you install Skype for Business Server or at the same time you install a Skype for Business Server role that requires a database back end. After the databases have been installed, you will rarely need to uninstall them.

However, it is possible that you might need to uninstall a Skype for Business Server database at some point; for example, a hardware failure or an issue with network connectivity might make an existing database unusable. Regardless of the reason, the Uninstall-CsDatabase cmdlet provides a way for you to remove or detach any of the SQL Server databases used by Skype for Business Server.

Examples

-------------------------- Example 1 --------------------------

Uninstall-CsDatabase -CentralManagementDatabase -SqlServerFqdn atl-sql-001.litwareinc.com

The command shown in Example 1 deletes the Central Management store from the computer atl-sql-001.litwareinc.com.

-------------------------- Example 2 --------------------------

Uninstall-CsDatabase -DatabaseType User -SqlServerFqdn atl-sql-001.litwareinc.com

In Example 2, the User database is deleted from the computer atl-sql-001.litwareinc.com. When you use the DatabaseType parameter, all stores related to the specified database are deleted.
