 ### SQL Server used by Azure AD Connect
 * Azure AD Connect requires a SQL Server database to store identity data. By default, a SQL Server 2019 Express LocalDB (a light version of SQL Server Express) is installed. SQL Server Express has a 10-GB size limit that enables you to manage approximately 100,000 objects. If you need to manage a higher volume of directory objects, point the installation wizard to a different installation of SQL Server. The type of SQL Server installation can impact the [performance of Azure AD Connect](./plan-connect-performance-factors.md#sql-database-factors).
 * If you use a different installation of SQL Server, these requirements apply:
-  * Azure AD Connect support all mainstream supported SQL Server versions up to SQL Server 2019. Please refer to the [SQL Server lifecycle article](/lifecycle/products/?products=sql-server) to verify the support status of your SQL Server version. Azure SQL Database *isn't supported* as a database.  This includes both Azure SQL Database and Azure SQL Managed Instance.

   * You must use a case-insensitive SQL collation. These collations are identified with a \_CI_ in their name. Using a case-sensitive collation identified by \_CS_ in their name *isn't supported*.
   * You can have only one sync engine per SQL instance. Sharing a SQL instance with FIM/MIM Sync, DirSync, or Azure AD Sync *isn't supported*.
